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