| <h3 class="section">5.6 <code>memchr</code>—find character in memory</h3> |
| |
| <p><a name="index-memchr-376"></a><strong>Synopsis</strong> |
| <pre class="example"> #include <string.h> |
| void *memchr(const void *<var>src</var>, int <var>c</var>, size_t <var>length</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| This function searches memory starting at <code>*</code><var>src</var> 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> |
| <strong>Returns</strong><br> |
| If the character <var>c</var> is found within <var>length</var> characters |
| of <code>*</code><var>src</var>, a pointer to the character is returned. If |
| <var>c</var> is not found, then <code>NULL</code> is returned. |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>memchr</code> is ANSI C. |
| |
| <p><code>memchr</code> requires no supporting OS subroutines. |
