C 4 strcmp - compare strings

#include <string.h>

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

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

Strcmp and strncmp compare null-terminated strings s1 and s2 and return an integer greater than, equal to, or less than 0, according as s1 is lexicographically greater than, equal to, or less than s2 . The comparison is done using unsigned characters, so that '\e200' is greater than '\e0'.

Strncmp compares at most len characters.

bcmp(3), memcmp(3), strcasecmp(3), strcoll(3), strxfrm(3) Strcmp and strncmp conform to ANSI X3.159-1989 (``ANSI C'').
