compareByteArrays# src1 src1_ofs src2 src2_ofs n
compares
n bytes starting at offset
src1_ofs in the
first
ByteArray# src1 to the range of
n bytes
(i.e. same length) starting at offset
src2_ofs of the second
ByteArray# src2. Both arrays must fully contain the
specified ranges, but this is not checked. Returns an
Int# less
than, equal to, or greater than zero if the range is found,
respectively, to be byte-wise lexicographically less than, to match,
or be greater than the second range.
Warning: this can fail with an unchecked exception.
