<H2>DESCRIPTION</H2>
|
|
|
|
The
|
|
<B>mkdtemp</B>()
|
|
|
|
function generates a uniquely named temporary
|
|
directory from <I>template</I>.
|
|
The last six characters of <I>template</I>
|
|
must be XXXXXX and these are replaced with a string that makes the
|
|
directory name unique.
|
|
The directory is then created with
|
|
permissions 0700.
|
|
Since it will be modified,
|
|
<I>template</I>
|
|
|
|
must not be a string constant, but should be declared as a character array.
|
|
<A NAME="lbAE"> </A>
|
|
<H2>RETURN VALUE</H2>
|
|
|
|
The
|
|
<B>mkdtemp</B>()
|
|
|
|
function returns a pointer to the modified template
|
|
string on success, and NULL on failure, in which case
|
|
<I>errno</I>
|
|
|
|
is set appropriately.

<DL COMPACT>
|
|
<DT id="2"><B>EINVAL</B>
|
|
|
|
<DD>
|
|
The last six characters of <I>template</I> were not XXXXXX.
|
|
Now <I>template</I> is unchanged.
