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* 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  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.

       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.
