| 25 | * Load parameters. |
| 26 | * |
| 27 | * This module provides suitable callback functions for the params |
| 28 | * module. It builds the internal table of service details which is |
| 29 | * then used by the rest of the server. |
| 30 | * |
| 31 | * To add a parameter: |
| 32 | * |
| 33 | * 1) add it to the global or service structure definition |
| 34 | * 2) add it to the parm_table |
| 35 | * 3) add it to the list of available functions (eg: using FN_GLOBAL_STRING()) |
| 36 | * 4) If it's a global then initialise it in init_globals. If a local |
| 37 | * (ie. service) parameter then initialise it in the sDefault structure |
| 38 | * |
| 39 | * |
| 40 | * Notes: |
| 41 | * The configuration file is processed sequentially for speed. It is NOT |
| 42 | * accessed randomly as happens in 'real' Windows. For this reason, there |
| 43 | * is a fair bit of sequence-dependent code here - ie., code which assumes |
| 44 | * that certain things happen before others. In particular, the code which |
| 45 | * happens at the boundary between sections is delicately poised, so be |
| 46 | * careful! |
