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 | * | |
aef68d78 | 31 | * 1) add it to the global_vars or local_vars 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()) | |
243e9a36 | 34 | * 4) initialise it in the Defaults static stucture |
0b76cd63 AT |
35 | * |
36 | * Notes: | |
8880d8ec WD |
37 | * The configuration file is processed sequentially for speed. For this |
38 | * reason, there is a fair bit of sequence-dependent code here - ie., code | |
39 | * which assumes that certain things happen before others. In particular, the | |
40 | * code which happens at the boundary between sections is delicately poised, | |
41 | * so be careful! | |
