references to <code class="code">basename name</code> (which is a relative file name)

The base name of the temporary file is formed by concatenating

The temporary file is created empty, with permissions <code class="code">0o600</code>

Same as <a href="Filename.html#VALtemp_file"><code class="code"><span class="constructor">Filename</span>.temp_file</code></a>, but returns both the name of a fresh
temporary file, and an output channel opened (atomically) on
this file. This function is more secure than <code class="code">temp_file</code>: there
is no risk that the temporary file will be modified (e.g. replaced
by a symbolic link) before the program opens it. The optional argument
<code class="code">mode</code> is a list of additional flags to control the opening of the file.
It can contain one or several of <code class="code"><span class="constructor">Open_append</span></code>, <code class="code"><span class="constructor">Open_binary</span></code>,

The name of the temporary directory:
