strncasecmp(3)                                           strncasecmp(3)

  strcasecmp()

  NAME

    strcasecmp(), strncasecmp() - compare strings, ignoring case

  SYNOPSIS

    #include 

    int strcasecmp (const char *s1, const char *s2)
    int strncasecmp (const char *s1, const char *s2, size_t len)

  DESCRIPTION

    The strcasecmp(3) and strncasecmp(3) functions compare the null-terminated
    strings s1 and s2 and return an integer greater than, equal to, or less
    than 0, if s1 is lexicographically greater than, equal to, or less than s2
    (respectively), after translating each corresponding character to lower-
    case. The strings themselves are not modified. The comparison is done
    using unsigned characters, so that \200 is greater than \0.

    The strncasecmp(3) compares at most len characters.
