DESCRIPTION    [Toc]    [Back]

       The  tmpfile()  function  creates  a  temporary  file  and
       returns its FILE pointer. The file is opened  for  update.
       The  temporary file is automatically deleted when the process
 using it terminates.

RETURN VALUES    [Toc]    [Back]

       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.

       for the following conditions:

       A signal  was  caught  during  tmpfile().   OPEN_MAX  file
       descriptors are currently open in the calling process.

              [Tru64  UNIX]  All  available  file descriptors are
              currently open in the calling process.  The maximum
              allowable  number of files is currently open in the
              system.  The directory or file  system  that  would
              contain the new file cannot be expanded.
