<h3>NAME
</h3> tmpnam - create a name for a temporary file
<h3>SYNOPSIS
</h3> #include <stdio.h>

overwritten by subsequent calls to tmpnam(). If s is not
NULL, the filename is returned in s.
<h3>RETURN VALUE
</h3> The tmpnam() function returns a pointer to the unique tem-
porary filename, or NULL if a unique name cannot be gener-
ated.
<h3>ERRORS
</h3> EEXIST Unable to generate a unique filename.
