<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>, or after <var>length</var> characters; in
|
|
particular, <code>NUL</code> does not terminate the search.
|
|
</p>
|
|
<br>
|
|
<p><strong>Returns</strong><br>
|
|
If the character <var>c</var> is found within <var>length</var> characters
|
|
of <code>*<var>src</var></code>, a pointer to the character is returned. If
|
|
<var>c</var> is not found, then <code>NULL</code> is returned.
|
|
</p>
|
|
<br>
|
|
<p><strong>Portability</strong><br>
|
|
<code>memchr</code> is ANSI C.
|
|
</p>
|
|
<p><code>memchr</code> requires no supporting OS subroutines.
