SYNOPSIS

#include <string.h>

int strcmp(const char *s1, const char *s2);

int strncmp(const char *s1, const char *s2, size_t n);

DESCRIPTION

The strcmp() function compares the two strings s1 and s2. It returns an integer less than, equal to, or greater than zero if s1 is found, respectively, to be less than, to match, or be greater than s2.

The strncmp() function is similar, except it compares the only first (at most) n bytes of s1 and s2.

RETURN VALUE

The strcmp() and strncmp() functions return an integer less than, equal to, or greater than zero if s1 (or the first n bytes thereof) is found, respectively, to be less than, to match, or be greater than s2.

ATTRIBUTES

Multithreading (see pthreads(7))

The strcmp() and strncmp() functions are thread-safe.
