optionFileLoad(3) Programmer's Manual optionFileLoad(3)
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 configura-
tion 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 di-
rectories 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Returns the value, "-1" if the program options descriptor is out of
date or indecipherable.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 re-
turned.
