25 | * This module provides suitable callback functions for the params | |
b583594a | 26 | * module. It builds the internal table of section details which is |
0b76cd63 AT |
27 | * then used by the rest of the server. |
28 | * | |
29 | * To add a parameter: | |
30 | * | |
b583594a | 31 | * 1) add it to the global or section structure definition |
0b76cd63 AT |
32 | * 2) add it to the parm_table |
33 | * 3) add it to the list of available functions (eg: using FN_GLOBAL_STRING()) | |
b583594a WD |
34 | * 4) If it's a global then initialise it in init_globals. If a local module |
35 | * (ie. section) parameter then initialise it in the sDefault structure | |
6464bdbe | 36 | * |
0b76cd63 AT |
37 | * |
38 | * Notes: | |
8880d8ec WD |
39 | * The configuration file is processed sequentially for speed. For this |
40 | * reason, there is a fair bit of sequence-dependent code here - ie., code | |
41 | * which assumes that certain things happen before others. In particular, the | |
42 | * code which happens at the boundary between sections is delicately poised, | |
43 | * so be careful! | |
