<h3>Name</h3>
strtok_r - tokenize string reentrantly

<h3>Library</h3>
Standard C Library (libc, -lc)

<h3>Synopsis</h3>
#include &lt;string.h&gt;<br>
<br>
char *<br>
strtok_r(char *<em>string</em>, const char *<em>separators</em>,
char **<em>context</em>);

<h3>Description</h3>

strtok_r is a reentrant version of <A HREF=strtok.html>strtok</A>. It
behaves the same way, except that the internal state is kept using the
<em>context</em> parameter rather than being global.
<p>

The value passed to the <em>context</em> parameter should be the
address of a char * whose value is preserved between successive
related calls to strtok_r. The char * need not be initialized
before the first call, and its value should not be inspected.
<p>

<h3>Return Values</h3>
strtok_r returns successive components of the passed-in string, and
NULL when no more remain.
