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.

Here is the sample code:
str1="abccccc"
str2="abc?"
if ]; then
echo "same string"
else
echo "different string"

Given that ? implies 0 or 1 match of preceding character, I was expecting the output to be "different string", but I am seeing "same string".
