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