STRCMP(3)                 OpenBSD Programmer's Manual                STRCMP(3)

NAME
     strcmp, strncmp - 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'.

     strncmp() compares at most len characters.

STANDARDS
     The strcmp() and strncmp() functions conform to ANSI X3.159-1989 (``ANSI
     C'').
