| <h3 class="section">5.29 <code>strncat</code>—concatenate strings</h3> |
| |
| <p><a name="index-strncat-397"></a><strong>Synopsis</strong> |
| <pre class="example"> #include <string.h> |
| char *strncat(char *restrict <var>dst</var>, const char *restrict <var>src</var>, |
| size_t <var>length</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| <code>strncat</code> appends not more than <var>length</var> characters from |
| the string pointed to by <var>src</var> (including the terminating |
| null character) to the end of the string pointed to by |
| <var>dst</var>. The initial character of <var>src</var> overwrites the null |
| character at the end of <var>dst</var>. A terminating null character |
| is always appended to the result |
| |
| <p><br> |
| <strong>Warnings</strong><br> |
| Note that a null is always appended, so that if the copy is |
| limited by the <var>length</var> argument, the number of characters |
| appended to <var>dst</var> is <code>n + 1</code>. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| This function returns the initial value of <var>dst</var> |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>strncat</code> is ANSI C. |
| |
| <p><code>strncat</code> requires no supporting OS subroutines. |
