26 * Load parameters.
27 *
28 * This module provides suitable callback functions for the params
29 * module. It builds the internal table of service details which is
30 * then used by the rest of the server.
31 *
32 * To add a parameter:
33 *
34 * 1) add it to the global or service structure definition
35 * 2) add it to the parm_table
36 * 3) add it to the list of available functions (eg: using FN_GLOBAL_STRING())
37 * 4) If it's a global then initialise it in init_globals. If a local
38 * (ie. service) parameter then initialise it in the sDefault structure
39 *
40 *
41 * Notes:
42 * The configuration file is processed sequentially for speed. It is NOT
43 * accessed randomly as happens in 'real' Windows. For this reason, there
44 * is a fair bit of sequence-dependent code here - ie., code which assumes
45 * that certain things happen before others. In particular, the code which
46 * happens at the boundary between sections is delicately poised, so be
47 * careful!
