NAME

       tmpfile() - create a temporary file

SYNOPSIS

DESCRIPTION

       creates	a temporary file by generating a name through (see tmpnam(3S)), and returns a corresponding pointer.  If the file cannot be opened
       a NULL pointer is returned.  The file is automatically deleted when the process using it terminates.  The file is opened for update

   Notes
       On HP-UX systems, the mode is equivalent to the mode.

ERRORS

       The function will fail if:

	      [EOVERFLOW]	       The named file is a regular file and the size of the file cannot be represented correctly in an	object	of
				       size in this environment.

       Additional values may be set by the underlying function (see fopen(3S)).

NAME

       tmpfile - create a temporary file

SYNOPSIS

       #include <stdio.h>

       FILE *tmpfile(void);

DESCRIPTION

       The  tmpfile()  function creates a temporary file and opens a corresponding stream.  The file will automatically be deleted when all refer-
       ences to the file are closed.  The file is opened as in fopen(3C) for update (w+).

       The largest value that can be represented correctly in an object of type off_t will be established as the offset maximum in the	open  file
       description.

RETURN VALUES

       Upon successful completion, tmpfile() 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 will fail if:

       EINTR	       A signal was caught during the execution of tmpfile().

       EMFILE	       There are OPEN_MAX file descriptors currently open in the calling process.

       ENFILE	       The maximum allowable number of files is currently open in the system.

       ENOSPC	       The directory or file system which would contain the new file cannot be expanded.

       The tmpfile() function may fail if:

       EMFILE	       There are FOPEN_MAX streams currently open in the calling process.

       ENOMEM	       Insufficient storage space is available.

USAGE

       The stream refers to a file which is unlinked.  If the process is killed in the period between file creation  and  unlinking,  a  permanent
       file may be left behind.

       The tmpfile() function has a transitional interface for 64-bit file offsets. See lf64(5).
