NAME

       tmpfile - create a temporary file

SYNOPSIS

       #include <stdio.h>

       FILE *tmpfile (void);

DESCRIPTION

       The  tmpfile()  function  generates a unique temporary filename using the path prefix P_tmpdir defined in
       <stdio.h>.  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.

RETURN VALUE

       The  tmpfile()  function returns a stream descriptor, or NULL if a unique filename cannot be generated or
       the unique file cannot be opened.

ERRORS

       EACCES Search permission denied for directory in file's path prefix.
