| |
| <p><a name="index-fgetws-174"></a><a name="index-g_t_005ffgetws_005fr-175"></a><strong>Synopsis</strong> |
| <pre class="example"> #include <wchar.h> |
| wchar_t *fgetws(wchar_t *<var>ws</var>, int <var>n</var>, FILE *<var>fp</var>); |
| |
| #include <wchar.h> |
| wchar_t *_fgetws_r(struct _reent *<var>ptr</var>, wchar_t *<var>ws</var>, int <var>n</var>, FILE *<var>fp</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| Reads at most <var>n-1</var> wide characters from <var>fp</var> until a newline |
| is found. The wide characters including to the newline are stored |
| in <var>ws</var>. The buffer is terminated with a 0. |
| |
| <p>The <code>_fgetws_r</code> function is simply the reentrant version of |
| <code>fgetws</code> and is passed an additional reentrancy structure |
| pointer: <var>ptr</var>. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| <code>fgetws</code> returns the buffer passed to it, with the data |
| filled in. If end of file occurs with some data already |
| accumulated, the data is returned with no other indication. If |
| no data are read, NULL is returned instead. |
