strneqvcmp

strneqvcmp(3)							Programmer's Manual						     strneqvcmp(3)

NAME

       strneqvcmp - compare two strings with an equivalence mapping

SYNOPSIS

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

       int strneqvcmp(char const* str1, char const* str2, int ct);

DESCRIPTION

       Using  a  character  mapping, two strings are compared for "equivalence".  Each input character is mapped to a comparison character and the
       mapped-to characters are compared for the two NUL terminated input strings.  The comparison is limited to ct bytes.  This function name	is
       mapped to option_strneqvcmp so as to not conflict with the POSIX name space.

       str1   first string

       str2   second string

       ct     compare length

RETURN VALUE

       the difference between two differing characters

ERRORS

       none checked.  Caller responsible for seg faults.
