DESCRIPTION
       The  tmpfile()  function	 creates a temporary file and returns its FILE

       Upon successful completion, the tmpfile() function returns a pointer to
       the stream of the file that is created. Otherwise, it  returns  a  null
       pointer and sets errno to indicate the error.

ERRORS
       The  tmpfile() function sets errno to the specified values for the fol‐
       lowing conditions:
