STRCMP(3) BSD Programmer's Manual STRCMP(3)NAME
strcmp - compare strings
SYNOPSIS
#include <string.h>
int
strcmp(const char *s1, const char *s2);
int
strncmp(const char *s1, const char *s2, size_t len);
DESCRIPTION
The strcmp() and strncmp() functions lexicographically compare the null-
terminated strings s1 and s2.
RETURN VALUES
The strcmp() and strncmp() return an integer greater than, equal to, or
less than 0, according as the string s1 is greater than, equal to, or
less than the string s2. The comparison is done using unsigned charac-
ters, so that `\200' is greater than `\0'.
The strncmp() compares not more than len characters.
SEE ALSObcmp(3), memcmp(3), strcasecmp(3), strcoll(3), strxfrm(3)STANDARDS
The strcmp() and strncmp() functions conform to ANSI C X3.159-1989
