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

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
