|
|
<a name="index-file_002c-symbolic-link"></a>
|
|
|
|
<p>This section documents the behavior of GNU Fortran for file operations on
|
|
symbolic links, on systems that support them.
|
|
</p>
|
|
<ul>
|
|
<li> Results of INQUIRE statements of the “inquire by file” form will
|
|
relate to the target of the symbolic link. For example,
|
|
<code>INQUIRE(FILE="foo",EXIST=ex)</code> will set <var>ex</var> to <var>.true.</var> if
|
|
<var>foo</var> is a symbolic link pointing to an existing file, and <var>.false.</var>
|
|
if <var>foo</var> points to an non-existing file (“dangling” symbolic link).
|
|
|
|
</li><li> Using the <code>OPEN</code> statement with a <code>STATUS="NEW"</code> specifier
|
|
on a symbolic link will result in an error condition, whether the symbolic
|
|
link points to an existing target or is dangling.
|
|
|
|
</li><li> If a symbolic link was connected, using the <code>CLOSE</code> statement
|
|
with a <code>STATUS="DELETE"</code> specifier will cause the symbolic link itself
|
|
to be deleted, not its target.
|
|
|
|
</li></ul>
