strcmp(3)                                                     strcmp(3)

  strcmp()

  NAME

    strcmp(), strncmp() - compare strings

  SYNOPSIS

    #include 

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

  DESCRIPTION

    The strcmp(3) and strncmp(3) functions lexicographically compare the NUL-
    terminated strings s1 and s2.

  RETURN VALUES

    The strcmp(3) and strncmp(3) 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.

    Unlike strcmp(3), strncmp(3) compares not more than len characters.
