NAME

       optionProcess - this is the main option processing routine

SYNOPSIS

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

       int optionProcess(tOptions * opts, int a_ct, char ** a_v);

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 completely 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.

       opts   program options descriptor

       a_ct   program arg count

       a_v    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.
