tmpfile - Creates a temporary file

SYNOPSIS

       resource tmpfile (void  )

DESCRIPTION

	Creates a temporary file with a unique name in read-write (w+) mode and returns a file handle .

	The  file  is  automatically removed when closed (for example, by calling fclose(3), or when there are no remaining references to the file
       handle returned by tmpfile(3)), or when the script ends.

	For details, consult your system documentation on the tmpfile(3) function, as well as the stdio.h header file.

RETURN VALUES

	Returns a file handle, similar to the one returned by fopen(3), for the new file or FALSE on failure.

EXAMPLES

       Example #1

	      tmpfile(3) example

	      <?php
	      $temp = tmpfile();
	      fwrite($temp, "writing to tempfile");
	      fseek($temp, 0);
	      echo fread($temp, 1024);
	      fclose($temp); // this removes the file
	      ?>

	      The above example will output:

	      writing to tempfile

NAME

       tmpfile - create a temporary file

SYNOPSIS

       #include <stdio.h>

       FILE *tmpfile(void);

DESCRIPTION

       The  tmpfile()  function  opens a unique temporary file 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.
       In the latter case, errno is set to indicate the error.

ERRORS

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

       EEXIST Unable to generate a unique filename.

       EINTR  The call was interrupted by a signal.

       EMFILE Too many file descriptors in use by the process.

       ENFILE Too many files open in the system.

       ENOSPC There was no room in the directory to add the new filename.

       EROFS  Read-only file system.

CONFORMING TO

       SVr4, 4.3BSD, C89, C99, SUSv2, POSIX.1-2001.

NOTES

       POSIX.1-2001 specifies: an error message may be written to stdout if the stream cannot be opened.

       The  standard does not specify the directory that tmpfile() will use.  Glibc will try the path prefix P_tmpdir defined in <stdio.h>, and if
       that fails the directory /tmp.
