<h3>TMPFILE(3)          Linux Programmer's Manual          TMPFILE(3)
</h3>

<h3>NAME
</h3>       tmpfile - create a temporary file

<h3>SYNOPSIS
</h3>       #include &lt;stdio.h&gt;

       FILE *tmpfile (void);

<h3>DESCRIPTION
</h3>       The  tmpfile() function generates a unique temporary file-
       name using the path prefix P_tmpdir defined in  &lt;stdio.h&gt;.
       The  temporary  file  is  then opened in binary read/write
       (w+b) mode.  The file will be automatically  deleted  when
       it is closed or the program terminates.

<h3>RETURN VALUE
</h3>       The  tmpfile()  function  returns  a stream descriptor, or
       NULL if a unique  filename  cannot  be  generated  or  the
       unique file cannot be opened.

<h3>ERRORS
</h3>       EACCES Search  permission  denied  for directory in file's
              path prefix.

       EEXIST Unable to generate a unique filename.

       EMFILE Too many file descriptors in use by process.

       ENFILE Too many files open in system.

       EROFS  Read-only filesystem.
