<p><strong>Description</strong><br>
|
||
|
|
<code>wcsdup</code> allocates a new wide character string using <code>malloc</code>,
|
||
|
|
and copies the content of the argument <var>str</var> into the newly
|
||
|
|
allocated string, thus making a copy of <var>str</var>.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
<code>wcsdup</code> returns a pointer to the copy of <var>str</var> if enough
|
||
|
|
memory for the copy was available. Otherwise it returns NULL
|
||
|
|
and errno is set to ENOMEM.
