<p><strong>Synopsis</strong>
|
||
|
|
</p><div class="example">
|
||
|
|
<pre class="example">#include <string.h>
|
||
|
|
void *rawmemchr(const void *<var>src</var>, int <var>c</var>);

|
<p><strong>Description</strong><br>
|
||
|
|
This function searches memory starting at <code>*<var>src</var></code> for the
|
||
|
|
character <var>c</var>. The search only ends with the first occurrence
|
||
|
|
of <var>c</var>; in particular, <code>NUL</code> does not terminate the search.
|
||
|
|
No bounds checking is performed, so this function should only
|
||
|
|
be used when it is certain that the character <var>c</var> will be found.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
A pointer to the first occurance of character <var>c</var>.
|
||
|
|
