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.
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
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
