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!
