# [NAME](#NAME)

streqvcmp - compare two strings with an equivalence mapping

# [SYNOPSIS](#SYNOPSIS)

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

int **streqvcmp**(char const * *str1*, char const * *str2*);

# [DESCRIPTION](#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. This function name is mapped to option\_streqvcmp so as to not conflict with the POSIX name space.

[*str1*](#str1)

first string

[*str2*](#str2)

second string

# [RETURN VALUE](#RETURN_VALUE)

the difference between two differing characters

# [ERRORS](#ERRORS)

none checked. Caller responsible for seg faults.
