NAME

       optionSaveFile - saves the option state to a file

SYNOPSIS

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

       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 mes-
       sage will be printed to stderr and the routine will return.

optionProcess(3)						Programmer's Manual						  optionProcess(3)

NAME

       optionProcess - this is the main option processing routine

SYNOPSIS

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

       int optionProcess(tOptions* pOpts, int argc, char** argv);

DESCRIPTION

       This  is  the main entry point for processing options.  It is intended that this procedure be called once at the beginning of the execution
       of a program.  Depending on options selected earlier, it is sometimes necessary to stop and restart option processing, or  to  select  com-
       pletely different sets of options.  This can be done easily, but you generally do not want to do this.

       The number of arguments processed always includes the program name.  If one of the arguments is "--", then it is counted and the processing
       stops.  If an error was encountered and errors are to be tolerated, then the returned value is the index of the argument causing the error.
       A  hyphen  by itself ("-") will also cause processing to stop and will not be counted among the processed arguments.  A hyphen by itself is
       treated as an operand.  Encountering an operand stops option processing.

       pOpts  program options descriptor

       argc   program arg count

       argv   program arg vector

RETURN VALUE

       the count of the arguments processed

ERRORS

       Errors will cause diagnostics to be printed.  exit(3) may or may not be called.	It depends upon whether or not the options were  generated
       with the "allow-errors" attribute, or if the ERRSKIP_OPTERR or ERRSTOP_OPTERR macros were invoked.
