| <h3 class="section">4.39 <code>getw</code>—read a word (int)</h3> |
| |
| <p><a name="index-getw-227"></a><strong>Synopsis</strong> |
| <pre class="example"> #include <stdio.h> |
| int getw(FILE *<var>fp</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| <code>getw</code> is a function, defined in <code>stdio.h</code>. You can use <code>getw</code> |
| to get the next word from the file or stream identified by <var>fp</var>. As |
| a side effect, <code>getw</code> advances the file's current position |
| indicator. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| The next word (read as an <code>int</code>), unless there is no more |
| data or the host system reports a read error; in either of these |
| situations, <code>getw</code> returns <code>EOF</code>. Since <code>EOF</code> is a valid |
| <code>int</code>, you must use <code>ferror</code> or <code>feof</code> to distinguish these |
| situations. |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>getw</code> is a remnant of K&R C; it is not part of any ISO C Standard. |
| <code>fread</code> should be used instead. In fact, this implementation of |
| <code>getw</code> is based upon <code>fread</code>. |
| |
| <p>Supporting OS subroutines required: <code>fread</code>. |
