AutoGen - The Automated Program Generator: 7.8.1 local-only use

7.8.1 local-only use

To use AutoOpts in your application where you do not have to worry about distribution issues, your issues are simple and few.

Create a file `myopts.def', according to the documentation above. It is probably easiest to start with the example in Quick Start and edit it into the form you need.
Run AutoGen to create the option interface file (myopts.h) and the option descriptor code (myopts.c):
autogen myopts.def
In all your source files where you need to refer to option state, #include "myopts.h".

In your main routine, code something along the lines of:

#define ARGC_MIN some-lower-limit
#define ARGC_MAX some-upper-limit
main( int argc, char** argv )
{
    {
        int arg_ct = optionProcess( &myprogOptions, argc, argv );
        argc -= arg_ct;
        if ((argc < ARGC_MIN) || (argc > ARGC_MAX)) {
            fprintf( stderr, "%s ERROR:  remaining args (%d) "
                     "out of range\n", myprogOptions.pzProgName,
                     argc );

            USAGE( EXIT_FAILURE );
        }
        argv += arg_ct;
    }
    if (HAVE_OPT(OPTN_NAME))
        respond_to_optn_name();
    ...
}

Compile `myopts.c' and link your program with the following additional arguments:
myopts.c -I$prefix/include -L $prefix/lib -lopts
These values can be derived from the "autoopts-config" script:
myopts.c `autoopts-config cflags` `autoopts-config ldflags`
