NAME

optionSaveFile - saves the option state to a file

SYNOPSIS

#include < your-opts.h >
cc [...] -o outfile infile.c -l opts [...]

void optionSaveFile (tOptions * opts );

DESCRIPTION

This routine will save the state of option processing to a file. The name of that file can be specified with the argument to the --save-opts option, or by appending the rcfile attribute to the last homerc attribute. If no rcfile attribute was specified, it will default to . programname rc . If you wish to specify another file, you should invoke the SET_OPT_SAVE_OPTS( filename ) macro.

The recommend usage is as follows:
optionProcess(&progOptions, argc, argv);
if (i_want_a_non_standard_place_for_this)
SET_OPT_SAVE_OPTS("myfilename");
optionSaveFile(&progOptions);

opts

program options descriptor

ERRORS

If no homerc file was specified, this routine will silently return and do nothing. If the output file cannot be created or updated, a message will be printed to stderr and the routine will return.
