24 | * Load parameters. | |
25 | * | |
26 | * This module provides suitable callback functions for the params | |
27 | * module. It builds the internal table of service details which is | |
28 | * then used by the rest of the server. | |
29 | * | |
30 | * To add a parameter: | |
31 | * | |
32 | * 1) add it to the global or service structure definition | |
33 | * 2) add it to the parm_table | |
34 | * 3) add it to the list of available functions (eg: using FN_GLOBAL_STRING()) | |
35 | * 4) If it's a global then initialise it in init_globals. If a local | |
36 | * (ie. service) parameter then initialise it in the sDefault structure | |

38 | * |
39 | * Notes: | |
40 | * The configuration file is processed sequentially for speed. It is NOT | |
41 | * accessed randomly as happens in 'real' Windows. For this reason, there | |
42 | * is a fair bit of sequence-dependent code here - ie., code which assumes | |
43 | * that certain things happen before others. In particular, the code which | |
44 | * happens at the boundary between sections is delicately poised, so be | |
45 | * careful! | |
