It builds the internal table of service details which is * then used by the rest of the server. * * To add a parameter: * * 1) add it to the global or service structure definition * 2) add it to the parm_table * 3) add it to the list of available functions (eg: using FN_GLOBAL_STRING()) * 4) If it's a global then initialise it in init_globals. If a local * (ie. service) parameter then initialise it in the sDefault structure * * * Notes: * The configuration file is processed sequentially for speed. It is NOT * accessed randomly as happens in 'real' Windows. For this reason, there * is a fair bit of sequence-dependent code here - ie., code which assumes * that certain things happen before others. In particular, the code which * happens at the boundary between sections is delicately poised, so be * careful! * */ #include "includes.h" #include "params.h" #include "loadparm.h" #include "pcap.h"
