STRCMP(3)                BSD Library Functions Manual                STRCMP(3)

NAME
     strcmp, strncmp -- compare strings

LIBRARY
     Standard C Library (libc, -lc)

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 nul-
     terminated strings s1 and s2.

RETURN VALUES
     The strcmp() and strncmp() return an integer greater than, equal to, or
     less than 0, according to whether the string s1 is greater than, equal
     to, or less than the string s2.  The comparison is done using unsigned
     characters, so that '\200' is greater than '\0'.

     The strncmp() compares not more than len characters.

SEE ALSO
     bcmp(3), memcmp(3), strcasecmp(3), strcoll(3), strxfrm(3)

STANDARDS
     The strcmp() and strncmp() functions conform to ANSI X3.159-1989
     (``ANSI C89'').

NOTES
     If len is zero strncmp() returns always 0.
