NAME
optionFileLoad - Load the locatable config files, in order SYNOPSIS
#include <your-opts.h> cc [...] -o outfile infile.c -lopts [...] int optionFileLoad(tOptions* opts, char const* prog); DESCRIPTION
This function looks in all the specified directories for a configuration file ("rc" file or "ini" file) and processes any found twice. The first time through, they are processed in reverse order (last file first). At that time, only "immediate action" configurables are pro- cessed. For example, if the last named file specifies not processing any more configuration files, then no more configuration files will be processed. Such an option in the first named directory will have no effect. Once the immediate action configurables have been handled, then the directories are handled in normal, forward order. In that way, later config files can override the settings of earlier config files. See the AutoOpts documentation for a thorough discussion of the config file format. Configuration files not found or not decipherable are simply ignored. opts program options descriptor prog program name RETURN VALUE
0 -> SUCCESS, -1 -> FAILURE ERRORS
Returns the value, "-1" if the program options descriptor is out of date or indecipherable. Otherwise, the value "0" will always be returned. SEE ALSO
