<h3>Description</h3>
|
|
<p>
|
|
The two memory regions <em>block1</em> and <em>block2</em>, both of
|
|
length <em>len</em>, are compared lexicographically.
|
|
</p>
|
|
|
|
<h3>Return Values</h3>
|
|
<p>
|
|
If <em>block1</em> sorts before <em>block2</em>, -1 is returned.
|
|
</p>
|
|
<p>
|
|
If <em>block1</em> sorts after <em>block2</em>, 1 is returned.
|
|
</p>
|
|
<p>
|
|
If <em>block1</em> is the same as <em>block2</em>, 0 is returned.
|
|
</p>
|
|
|
|
<p>
|
|
The sort order used is derived from the natural ordering of
|
|
the numerical values of (unsigned) characters.
