23: /* Load parameters.
24: *
25: * This module provides suitable callback functions for the params
26: * module. It builds the internal table of service details which is
27: * then used by the rest of the server.
28: *
29: * To add a parameter:
30: *
31: * 1) add it to the global or service structure definition
32: * 2) add it to the parm_table
33: * 3) add it to the list of available functions (eg: using FN_GLOBAL_STRING())
34: * 4) If it's a global then initialise it in init_globals. If a local
35: * (ie. service) parameter then initialise it in the sDefault structure
36: *
37: *
38: * Notes:
39: * The configuration file is processed sequentially for speed. It is NOT
40: * accessed randomly as happens in 'real' Windows. For this reason, there
41: * is a fair bit of sequence-dependent code here - ie., code which assumes
42: * that certain things happen before others. In particular, the code which
43: * happens at the boundary between sections is delicately poised, so be
44: * careful!
