.SH NAME
optionFileLoad - Load the locatable config files, in order
.sp 1
.SH SYNOPSIS

#include <\fIyour-opts.h\fP>
.br
cc [...] -o outfile infile.c -l\fBopts\fP [...]
.sp 1
int \fBoptionFileLoad\fP(tOptions * \fIopts\fP, char const * \fIprog\fP);
.sp 1
.SH 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 processed.  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 \fBfirst\fP 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.
