STRCMP(3)

Contents


NAME    [Toc]    [Back]

     strcmp, strncmp - compare strings

LIBRARY    [Toc]    [Back]

     Standard C Library (libc, -lc)

SYNOPSIS    [Toc]    [Back]

     #include <string.h>

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

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

DESCRIPTION    [Toc]    [Back]

     The strcmp() and strncmp() functions lexicographically compare the nullterminated
 strings s1 and s2.

RETURN VALUES    [Toc]    [Back]

     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 characters,
 so that `\200' is greater than `\0'.

     The strncmp() compares not more than len characters.

SEE ALSO    [Toc]    [Back]

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

STANDARDS    [Toc]    [Back]

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

NOTES    [Toc]    [Back]

     If len is zero strncmp() returns always 0.
