strcmp, strncmp —
#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()
  functions lexicographically compare the nul-terminated strings
  s1 and s2.
strcmp() and strncmp()
  functions 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() function compares not more
    than len characters.
strcmp() and strncmp()
  functions conform to ANSI X3.159-1989
  (“ANSI C89”).
strncmp() always
  returns 0.
