30 | * getaddrinfo.h | |
31 | * Support getaddrinfo() on platforms that don't have it. | |
32 | * | |
33 | * Note: we use our own routines on platforms that don't HAVE_STRUCT_ADDRINFO, | |
34 | * whether or not the library routine getaddrinfo() can be found. This | |
35 | * policy is needed because on some platforms a manually installed libbind.a | |
36 | * may provide getaddrinfo(), yet the system headers may not provide the | |
37 | * struct definitions needed to call it. To avoid conflict with the libbind | |
38 | * definition in such cases, we rename our routines to pg_xxx() via macros. | |
39 | * | |
40 | * This code will also work on platforms where struct addrinfo is defined | |
41 | * in the system headers but no getaddrinfo() can be located. | |
