- - don't use mmap anymore (its lack of portability isn't worth the
- trouble)
- - added test script
- - added support for exec
- - removed support for *_POPT_ALIASES env variable -- it was a bad
- idea
- - reorganized into multiple source files
- - added automatic help generation, POPT_AUTOHELP
- - added table callbacks
- - added table inclusion
- - updated man page for new features
- - added test scripts
-
-1.0 -> 1.1

-.SH DESCRIPTION
-The popt library exists essentially for parsing command-line
-options. It is found superior in many ways when compared to
-parsing the argv array by hand or using the getopt functions
-.B getopt()
-and
-.B getopt_long()
-[see
-.BR getopt "(3)]."
-Some specific advantages of popt are: it does not utilize global
-.RI "variables, thus enabling multiple passes in parsing " argv
-.RI "; it can parse an arbitrary array of " argv "-style elements, "
-allowing parsing of command-line-strings from any source;
-it provides a standard method of option aliasing (to be
-discussed at length below.); it can exec external option filters; and,
-finally, it can automatically generate help and usage messages for
-the application.
-.sp
-Like
-.BR getopt_long() ,
-the popt library supports short and long style options. Recall
-that a
-.B short option
-consists of a - character followed by a single alphanumeric character.
-A
-.BR "long option" ,
-common in GNU utilities, consists of two - characters followed by a
-string made up of letters, numbers and hyphens. Long options are
-optionally allowed to begin with a single -, primarily to allow command-line
-compatibility between popt applications and X toolkit applications.
-Either type of option may be followed by an argument. A space separates a
-short option from its arguments; either a space or an = separates a long
-option from an argument.
-.sp
-The popt library is highly portable and should work on any POSIX
-platform. The latest version is always available from:
-ftp://ftp.redhat.com/pub/redhat/code/popt.
-.sp
-It may be redistributed under either the GNU General Public License
-or the GNU Library General Public License, at the distributor's discretion.
-.SH "BASIC POPT USAGE"
-.SS "1. THE OPTION TABLE"
-Applications provide popt with information on their command-line
-options by means of an "option table," i.e., an array of
-.B struct poptOption
-structures:
-.sp
-#include <popt.h>
-.sp
-.nf
-struct poptOption {
- const char * longName; /* may be NULL */
- char shortName; /* may be '\\0' */
- int argInfo;
- void * arg; /* depends on argInfo */
- int val; /* 0 means don't return, just update flag */
- char * descrip; /* description for autohelp -- may be NULL */
- char * argDescrip; /* argument description for autohelp */
-};
-.fi
-.sp
-Each member of the table defines a single option that may be
-passed to the program. Long and short options are considered
-a single option that may occur in two different forms. The
-first two members,
-.IR longName " and " shortName ", define the names of the option;"
-the first is a long name, while the latter is a single character.
-.sp
-The
-.IR argInfo " member tell popt what type of argument is expected"
-after the argument. If no option is expected,
-.BR POPT_ARG_NONE " should be used. (Connoisseurs of " getopt()
-.RI "will note that " argInfo " is the only required field of "
-.BR "struct poptOption" " that is not directly analogous to a field in "
-.RB "the " getopt_long() " argument table. The similarity between the "
-.RB "two allows for easy transitions from " getopt_long " to popt.) "
-The rest of the valid values are shown in the following table:
-.sp
-.nf
-.B " Value Description arg Type"
-.BR POPT_ARG_NONE " No argument expected int"
-.BR POPT_ARG_STRING " No type checking to be performed char *"
-.BR POPT_ARG_INT " An integer argument is expected int"
-.BR POPT_ARG_LONG " A long integer is expected long"
-.sp
-.fi
-If \fIargInfo\fR value is logically or'd with \fBPOPT_ARGFLAG_ONEDASH\fR,
-the long argument may be given with a single - instead of two. For example,
-if \fB--longopt\fR is an option with \fBPOPT_ARGFLAG_ONEDASH\fR, is
-specified, \fB-longopt\fR is accepted as well.
-.sp
-.RI "The next element, " arg ", allows popt to automatically update "
-.RI "program variables when the option is used. If " arg " is "
-.BR NULL ", it is ignored and popt takes no special action. "
-Otherwise it should point to a variable of the type indicated in the
-right-most column of the table above.
-.sp
-.RI "If the option takes no argument (" argInfo " is "
-.BR POPT_ARG_NONE "), the variable pointed to by "
-.IR arg " is set to 1 when the option is used. (Incidentally, it "
-will perhaps not escape the attention of hunt-and-peck typists that
-.RB "the value of " POPT_ARG_NONE " is 0.) If the option does take "
-an argument, the variable that
-.IR arg " points to is updated to reflect the value of the argument."
-.RB "Any string is acceptable for " POPT_ARG_STRING " arguments, but "
-.BR POPT_ARG_INT " and " POPT_ARG_LONG " are converted to the
-appropriate type, and an error returned if the conversion fails.
-.sp
-.RI "The next option, " val ", is the value popt's parsing function
-should return when the option is encountered. If it is 0, the parsing
-function does not return a value, instead parsing the next
-command-line argument.
-.sp
-.RI "The last two options, " descrip " and " argDescrip " are only required
-if automatic help messages are desired (automatic usage messages can
-.RI "be generated without them). " descrip " is a text description of the
-.RI "argument and " argdescrip " is a short summary of the type of arguments
-.RI "the option expects, or NULL if the option doesn't require any
-arguments.
-.sp
-.RB "If popt should automatically provide " --usage " and " --help " (" -? ")
-.RB "options, one line in the table should be the macro " POPT_AUTOHELP ".
-.RB "This macro includes another option table (via " POPT_ARG_INCLUDE_TABLE;
-see below) in the main one which provides the table entries for these
-.RB "arguments. When " --usage " or " --help " are passed to programs which
-use popt's automatical help, popt displays the appropriate message on
-stderr as soon as it finds the option, and exits the program with a
-return code of 0. If you want to use popt's automatic help generation in
-a different way, you need to explicitly add the option entries to your programs
-.RB "option table instead of using " POPT_AUTOHELP ".
-.sp
-The final structure in the table should have all the pointer values set
-.RB "to " NULL " and all the arithmetic values set to 0, marking the "
-end of the table.
-.sp
-There are two types of option table entries which do not specify command
-line options. When either of these types of entries are used, the
-\fIlongName\fR element must be \fBNULL\fR and the \fBshortName\fR element
-must be \fB'\\0'\fR.
-.sp
-The first of these special entry types allows the application to nest
-another option table in the current one; such nesting may extend quite
-deeply (the actual depth is limited by the program's stack). Including
-other option tables allows a library to provide a standard set of
-command-line options to every program which uses it (this is often done
-in graphical programming toolkits, for example). To do this, set
-the \fIargInfo\fR field to \fBPOPT_ARG_INCLUDE_TABLE\fR and the
-\fRarg\fR field to point to the table which is being included. If
-automatic help generation is being used, the \fIdescrip\fR field should
-contain a overall description of the option table being included.
-.sp
-The other special option table entry type tells popt to call a function (a
-callback) when any option in that table is found. This is especially usefull
-when included option tables are being used, as the program which provides
-the top-level option table doesn't need to be aware of the other options
-which are provided by the included table. When a callback is set for
-a table, the parsing function never returns information on an option in
-the table. Instead, options information must be retained via the callback
-or by having popt set a variable through the option's \fIarg\fR field.
-Option callbacks should match the following prototype:
-.sp
-.nf
-.BI "void poptCallbackType(poptContext con,
-.BI " const struct poptOption * opt,
-.BI " const char * arg, void * data);
-.fi
-.sp
-The first parameter is the context which is being parsed (see the next
-section for information on contexts), \fIopt\fR points to the option
-which triggered this callback, and \fIarg\fR is the option's argument.
-If the option does not take an argument, \fIarg\fR is \fBNULL\fR. The
-final parameter, \fIdata\fR is taken from the \fIdescrip\fR field
-of the option table entry which defined the callback. As \fIdescrip\fR
-is a pointer, this allows callback functions to be passed an arbitrary
-set of data (though a typecast will have to be used).
-.sp
-The option table entry which defines a callback has an \fIargInfo\fR of
-\fBPOPT_ARG_CALLBACK\fR, an \fIarg\fR which points to the callback
-function, and a \fIdescrip\fR field which specifies an arbitrary pointer
-to be passed to the callback.
-.SS "2. CREATING A CONTEXT"
-popt can interleave the parsing of multiple command-line sets. It allows
-this by keeping all the state information for a particular set of
-command-line arguments in a
-.BR poptContext " data structure, an opaque type that should not be "
-modified outside the popt library.
-.sp
-.RB "New popt contexts are created by " poptGetContext() ":"
-.sp
-.nf
-.BI "poptContext poptGetContext(char * " name ", int "argc ",
-.BI " char ** "argv ",
-.BI " struct poptOption * "options ",
-.BI " int "flags ");"
-.fi
-.sp
-The first parameter,
-.IR name ", is used only for alias handling (discussed later). It "
-should be the name of the application whose options are being parsed,
-.RB "or should be " NULL " if no option aliasing is desired. The next "
-two arguments specify the command-line arguments to parse. These are
-.RB "generally passed to " poptGetContext() " exactly as they were "
-.RB "passed to the program's " main() " function. The "
-.IR options " parameter points to the table of command-line options, "
-which was described in the previous section. The final parameter,
-.IR flags ",is not currently used but should always be specified as
-0 for compatibility with future versions of the popt library.
-.sp
-.RB "A " poptContext " keeps track of which options have already been "
-parsed and which remain, among other things. If a program wishes to
-restart option processing of a set of arguments, it can reset the
-.BR poptContext " by passing the context as the sole argument to "
-.BR poptResetContext() .
-.sp
-When argument processing is complete, the process should free the
-.BR poptContext " as it contains dynamically allocated components. The "
-.BR poptFreeContext() " function takes a "
-.BR poptContext " as its sole argument and frees the resources the "
-context is using.
-.sp
-.RB "Here are the prototypes of both " poptResetContext() " and "
-.BR poptFreeContext() :
-.sp
-.nf
-.B #include <popt.h>
-.BI "void poptFreeContext(poptContext " con ");"
-.BI "void poptResetContext(poptContext " con ");"
-.fi
-.sp
-.SS "3. PARSING THE COMMAND LINE"
-.RB "After an application has created a " poptContext ", it may begin "
-.RB "parsing arguments. " poptGetNextOpt() " performs the actual "
-argument parsing.
-.sp
-.nf
-.B #include <popt.h>
-.BI "int poptGetNextOpt(poptContext " con ");"
-.fi
-.sp
-Taking the context as its sole argument, this function parses the next
-command-line argument found. After finding the next argument in the
-option table, the function fills in the object pointed to by the option
-.RI "table entry's " arg
-.RB "pointer if it is not " NULL ". If the val entry for the option is "
-non-0, the function then returns that value. Otherwise,
-.BR poptGetNextOpt() " continues on to the next argument."
-.sp
-.BR poptGetNextOpt() " returns -1 when the final argument has been "
-parsed, and other negative values when errors occur. This makes it a
-good idea to
-.RI "keep the " val " elements in the options table greater than 0."
-.sp
-.RI "If all of the command-line options are handled through " arg
-pointers, command-line parsing is reduced to the following line of code:
-.sp
-.nf
-rc = poptGetNextOpt(poptcon);
-.fi
-.sp
-Many applications require more complex command-line parsing than this,
-however, and use the following structure:
-.sp
-.nf
-while ((rc = poptGetNextOpt(poptcon)) > 0) {
- switch (rc) {
- /* specific arguments are handled here */
- }
-}
-.fi
-.sp
-When returned options are handled, the application needs to know the
-value of any arguments that were specified after the option. There are two
-ways to discover them. One is to ask popt to fill in a variable with the
-.RI "value of the option through the option table's " arg " elements. The "
-.RB "other is to use " poptGetOptArg() ":"
-.sp
-.nf
-.B #include <popt.h>
-.BI "char * poptGetOptArg(poptContext " con ");"
-.fi
-.sp
-This function returns the argument given for the final option returned by
-.BR poptGetNextOpt() ", or it returns " NULL " if no argument was specified."
-.sp
-.SS "4. LEFTOVER ARGUMENTS"
-Many applications take an arbitrary number of command-line arguments,
-such as a list of file names. When popt encounters an argument that does
-not begin with a -, it assumes it is such an argument and adds it to a list
-of leftover arguments. Three functions allow applications to access such
-arguments:
-.nf
-.HP
-.BI "char * poptGetArg(poptContext " con ");"
-.fi
-This function returns the next leftover argument and marks it as
-processed.
-.PP
-.nf
-.HP
-.BI "char * poptPeekArg(poptContext " con ");"
-.fi
-The next leftover argument is returned but not marked as processed.
-This allows an application to look ahead into the argument list,
-without modifying the list.
-.PP
-.nf
-.HP
-.BI "char ** poptGetArgs(poptContext " con ");"
-.fi
-All the leftover arguments are returned in a manner identical to
-.IR argv ". The final element in the returned array points to "
-.BR NULL ", indicating the end of the arguments.
-.sp
-.SS "5. AUTOMATIC HELP MESSAGES"
-The \fBpopt\fR library can automatically generate help messages which
-describe the options a program accepts. There are two types of help
-messages which can be generated. Usage messages are a short messages
-which lists valid options, but does not describe them. Help messages
-describe each option on one (or more) lines, resulting in a longer, but
-more useful, message. Whenever automatic help messages are used, the
-\fBdescrip\fR and \fBargDescrip\fR fields \fBstruct poptOption\fR members
-should be filled in for each option.
-.sp
-The \fBPOPT_AUTOHELP\fR macro makes it easy to add \fB--usage\fR and
-\fB--help\fR messages to your program, and is described in part 1
-of this man page. If more control is needed over your help messages,
-the following two functions are available:
-.sp
-.nf
-.B #include <popt.h>
-.BI "void poptPrintHelp(poptContext " con ", FILE * " f ", int " flags ");
-.BI "void poptPrintUsage(poptContext " con ", FILE * " f ", int " flags ");
-.fi
-.sp
-\fBpoptPrintHelp()\fR displays the standard help message to the stdio file
-descriptor f, while \fBpoptPrintUsage()\fR displays the shorter usage
-message. Both functions currently ignore the \fBflags\fR argument; it is
-there to allow future changes.
-.sp
-.SH "ERROR HANDLING"
-All of the popt functions that can return errors return integers.
-When an error occurs, a negative error code is returned. The
-following table summarizes the error codes that occur:
-.sp
-.nf
-.B " Error Description"
-.BR "POPT_ERROR_NOARG " "Argument missing for an option."
-.BR "POPT_ERROR_BADOPT " "Option's argument couldn't be parsed."
-.BR "POPT_ERROR_OPTSTOODEEP " "Option aliasing nested too deeply."
-.BR "POPT_ERROR_BADQUOTE " "Quotations do not match."
-.BR "POPT_ERROR_BADNUMBER " "Option couldn't be converted to number."
-.BR "POPT_ERROR_OVERFLOW " "A given number was too big or small."
-.fi
-.sp
-Here is a more detailed discussion of each error:
-.sp
-.TP
-.B POPT_ERROR_NOARG
-An option that requires an argument was specified on the command
-line, but no argument was given. This can be returned only by
-.BR poptGetNextOpt() .
-.sp
-.TP
-.B POPT_ERROR_BADOPT
-.RI "An option was specified in " argv " but is not in the option
-.RB "table. This error can be returned only from " poptGetNextOpt() .
-.sp
-.TP
-.B POPT_ERROR_OPTSTOODEEP
-A set of option aliases is nested too deeply. Currently, popt
-follows options only 10 levels to prevent infinite recursion. Only
-.BR poptGetNextOpt() " can return this error."
-.sp
-.TP
-.B POPT_ERROR_BADQUOTE
-A parsed string has a quotation mismatch (such as a single quotation
-.RB "mark). " poptParseArgvString() ", " poptReadConfigFile() ", or "
-.BR poptReadDefaultConfig() " can return this error."
-.sp
-.TP
-.B POPT_ERROR_BADNUMBER
-A conversion from a string to a number (int or long) failed due
-to the string containing nonnumeric characters. This occurs when
-.BR poptGetNextOpt() " is processing an argument of type "
-.BR POPT_ARG_INT " or " POPT_ARG_LONG .
-.sp
-.TP
-.B POPT_ERROR_OVERFLOW
-A string-to-number conversion failed because the number was too
-.RB "large or too small. Like " POPT_ERROR_BADNUMBER ", this error
-.RB "can occur only when " poptGetNextOpt() " is processing an "
-.RB "argument of type " POPT_ARG_INT " or " POPT_ARG_LONG .
-.sp
-.TP
-.B POPT_ERROR_ERRNO
-.RI "A system call returned with an error, and " errno " still
-contains the error from the system call. Both
-.BR poptReadConfigFile() " and " poptReadDefaultConfig() " can "
-return this error.
-.sp
-.PP
-Two functions are available to make it easy for applications to provide
-good error messages.
-.HP
-.nf
-.BI "const char * poptStrerror(const int " error ");"
-.fi
-This function takes a popt error code and returns a string describing
-.RB "the error, just as with the standard " strerror() " function."
-.PP
-.HP
-.nf
-.BI "char * poptBadOption(poptContext " con ", int " flags ");"
-.fi
-.RB "If an error occurred during " poptGetNextOpt() ", this function "
-.RI "returns the option that caused the error. If the " flags " argument"
-.RB "is set to " POPT_BADOPTION_NOALIAS ", the outermost option is "
-.RI "returned. Otherwise, " flags " should be 0, and the option that is "
-returned may have been specified through an alias.
-.PP
-These two functions make popt error handling trivial for most
-applications. When an error is detected from most of the functions,
-an error message is printed along with the error string from
-.BR poptStrerror() ". When an error occurs during argument parsing, "
-code similiar to the following displays a useful error message:
-.sp
-.nf
-fprintf(stderr, "%s: %s\\n",
- poptBadOption(optCon, POPT_BADOPTION_NOALIAS),
- poptStrerror(rc));
-.fi
-.sp
-.SH "OPTION ALIASING"
-.RB "One of the primary benefits of using popt over " getopt() " is the "
-ability to use option aliasing. This lets the user specify options that
-popt expands into other options when they are specified. If the standard
-.RB "grep program made use of popt, users could add a " --text " option "
-.RB "that expanded to " "-i -n -E -2" " to let them more easily find "
-information in text files.
-.sp
-.SS "1. SPECIFYING ALIASES"
-.RI "Aliases are normally specified in two places: " /etc/popt
-.RB "and the " .popt " file in the user's home directory (found through "
-.RB "the " HOME " environment variable). Both files have the same format, "
-an arbitrary number of lines formatted like this:
-.sp
-.IB appname " alias " newoption "" " expansion"
-.sp
-.RI "The " appname " is the name of the application, which must be the "
-.RI "same as the " name " parameter passed to "
-.BR poptGetContext() ". This allows each file to specify aliases for "
-.RB "multiple programs. The " alias " keyword specifies that an alias is "
-being defined; currently popt configuration files support only aliases, but
-other abilities may be added in the future. The next option is the option
-that should be aliased, and it may be either a short or a long option. The
-rest of the line specifies the expansion for the alias. It is parsed
-similarly to a shell command, which allows \\, ", and ' to be used for
-quoting. If a backslash is the final character on a line, the next line
-in the file is assumed to be a logical continuation of the line containing
-the backslash, just as in shell.
-.sp
-.RB "The following entry would add a " --text " option to the grep command, "
-as suggested at the beginning of this section.
-.sp
-.B "grep alias --text -i -n -E -2"
-.SS "2. ENABLING ALIASES"
-.RB "An application must enable alias expansion for a " poptContext
-.RB "before calling " poptGetNextArg() " for the first time. There are "
-three functions that define aliases for a context:
-.HP
-.nf
-.BI "int poptReadDefaultConfig(poptContext " con ", int " flags ");"
-.fi
-.RI "This function reads aliases from " /etc/popt " and the "
-.BR .popt " file in the user's home directory. Currently, "
-.IR flags " should be "
-.BR NULL ", as it is provided only for future expansion."
-.PP
-.HP
-.nf
-.BI "int poptReadConfigFile(poptContext " con ", char * " fn ");"
-.fi
-.RI "The file specified by " fn " is opened and parsed as a popt "
-configuration file. This allows programs to use program-specific
-configuration files.
-.PP
-.HP
-.nf
-.BI "int poptAddAlias(poptContext " con ", struct poptAlias " alias ",
-.BI " int " flags ");"
-.fi
-Occasionally, processes want to specify aliases without having to
-read them from a configuration file. This function adds a new alias
-.RI "to a context. The " flags " argument should be 0, as it is "
-currently reserved for future expansion. The new alias is specified
-.RB "as a " "struct poptAlias" ", which is defined as:"
-.sp
-.nf
-struct poptAlias {
- char * longName; /* may be NULL */
- char shortName; /* may be '\\0' */
- int argc;
- char ** argv; /* must be free()able */
-};
-.fi
-.sp
-.RI "The first two elements, " longName " and " shortName ", specify "
-.RI "the option that is aliased. The final two, " argc " and " argv ","
-define the expansion to use when the aliases option is encountered.
-.PP
-.SH "PARSING ARGUMENT STRINGS"
-Although popt is usually used for parsing arguments already divided into
-.RI "an " argv "-style array, some programs need to parse strings that "
-are formatted identically to command lines. To facilitate this, popt
-provides a function that parses a string into an array of strings,
-using rules similiar to normal shell parsing.
-.sp
-.nf
-.B "#include <popt.h>"
-.BI "int poptParseArgvString(char * " s ", int * "argcPtr ",
-.BI " char *** " argvPtr ");"
-.fi
-.sp
-.RI "The string s is parsed into an " argv "-style array. The integer "
-.RI "pointed to by the second parameter, " argcPtr ", contains the number "
-of elements parsed, and the pointer pointed to by the final parameter is
-set to point to the newly created array. The array is dynamically
-.RB "allocated and should be " free() "ed when the application is finished "
-with it.
-.sp
-.RI "The " argvPtr
-.RB "created by " poptParseArgvString() " is suitable to pass directly "
-.RB "to " poptGetContext() .
-.SH "HANDLING EXTRA ARGUMENTS"
-Some applications implement the equivalent of option aliasing but need
-.RB "to do so through special logic. The " poptStuffArgs() " function "
-allows an application to insert new arguments into the current
-.BR poptContext .
-.sp
-.nf
-.B "#include <popt.h>"
-.BI "int poptStuffArgs(poptContext "con ", char ** " argv ");"
-.fi
-.sp
-.RI "The passed " argv
-.RB "must have a " NULL " pointer as its final element. When "
-.BR poptGetNextOpt() " is next called, the "
-"stuffed" arguments are the first to be parsed. popt returns to the
-normal arguments once all the stuffed arguments have been exhausted.
-.SH "EXAMPLE"
-The following example is a simplified version of the program "robin"
-which appears in Chapter 15 of the text cited below. Robin has
-been stripped of everything but its argument-parsing logic, slightly
-reworked, and renamed "parse." It may prove useful in illustrating
-at least some of the features of the extremely rich popt library.

-Popt is a C library for pasing command line parameters. It was heavily
-influenced by the getopt() and getopt_long() functions, but it allows
-more powerfull argument expansion. It can parse arbitrary argv[] style
-arrays and automatically set variables based on command line arguments.
-It also allows command line arguments to be aliased via configuration
-files and includes utility functions for parsing arbitrary strings into
-argv[] arrays using shell-like rules.

+1.3 ->
+ - heavy dose of const's
+ - poptParseArgvString() now NULL terminates the list
+
+1.2.3 -> 1.3
+ - added support for single -
+ - misc bug fixes
+ - portability improvements
+
+1.2.2 -> 1.2.3
+ - fixed memset() in help message generation (Dale Hawkins)
+ - added extern "C" stuff to popt.h for C++ compilers (Dale Hawkins)
+ - const'ified poptParseArgvString (Jeff Garzik)
+
+1.2.1 -> 1.2.2
+ - fixed bug in chaind alias happens which seems to have only
+ affected --triggers in rpm
+ - added POPT_ARG_VAL
+ - popt.3 installed by default
+
+1.2 -> 1.2.1
+ - added POPT_ARG_INTL_DOMAIN (Elliot Lee)
+ - updated Makefile's to be more GNUish (Elliot Lee)
+
+1.1 -> 1.2
+ - added popt.3 man page (Robert Lynch)
+ - don't use mmap anymore (its lack of portability isn't worth the
+ trouble)
+ - added test script
+ - added support for exec
+ - removed support for *_POPT_ALIASES env variable -- it was a bad
+ idea
+ - reorganized into multiple source files
+ - added automatic help generation, POPT_AUTOHELP
+ - added table callbacks
+ - added table inclusion
+ - updated man page for new features
+ - added test scripts
+
+1.0 -> 1.1
+ - moved to autoconf (Fred Fish)
+ - added STRERROR replacement (Norbert Warmuth)
+ - added const keywords (Bruce Perens)
