Clib.memcmp() Method

This method compares the contents of two buffers or the length of two buffers.

Syntax

Clib.memcmp(buf1, buf2[, length])

Returns

A negative number if buf1 is less than buf2, 0 if buf1 is the same as buf2 for length bytes, a positive number if buf1 is greater than buf2.

Usage

If length is not specified, Clib.memcmp() compares the length of the two buffers. It then compares the contents up to the length of the shorter buffer. If length is specified and one of the buffers is shorter than length, comparison proceeds up to the length of the shorter buffer.
