Compares byte strings.

    Format

      #include  <strings.h>

      void bcmp  (const void *string1, const void *string2, size_t length);

1 - Arguments

 string1, string2

    The byte strings to be compared.

 length

    The length (in bytes) of the strings.

2 - Description

    The bcmp function compares the byte string in string1 against the
    byte string in string2.

    Unlike the string functions, there is no checking for null bytes.
    Zero-length strings are always identical.

    Note that bcmp is equivalent to memcmp, which is defined by
    the ANSI C Standard. Therefore, using memcmp is recommended for
    portable programs.

3 - Return Values

    0                  The strings are identical.
    Nonzero            The strings are not identical.
