STRCMP(3)             DragonFly 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 null-
     terminated strings s1 and s2.

     The strncmp() function compares not more than len characters.  Because
     strncmp() is designed for comparing strings rather than binary data,
     characters that appear after a `\0' character are not compared.


RETURN VALUES

     The strcmp() and strncmp() functions 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'.


SEE ALSO

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


STANDARDS

     The strcmp() and strncmp() functions conform to ISO/IEC 9899:1990
     (``ISO C90'').
