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
. programnamerc. 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.
