Netpbm subroutine library: pm_tmpfile() function(3)	     Library Functions Manual	       Netpbm subroutine library: pm_tmpfile() function(3)

NAME

       pm_tmpfile() - create a temporary unnamed file

SYNOPSIS

       #include <netpbm/pm.h>

       FILE *
       pm_tmpfile(void);

EXAMPLE

       This simple example creates a temporary file, writes 'hello world' to it, then reads back and prints those contents.

       #include <netpbm/pm.h>

       FILE * myfileP;

       myfile = pm_tmpfile();

       fprintf(myfile, 'hello world
');

       fseek(myfileP, 0, SEEK_SET);

       fread(buffer, sizeof(buffer), 1, myfileP);

       fprintf(STDOUT, 'temp file contains '%s'
', buffer);

       fclose(myfileP);

DESCRIPTION

       This library function is part of Netpbm(1)

       pm_tmpfile()  creates  and  opens  an unnamed temporary file.  It is basically the same thing as the standard C library tmpfile() function,
       except that it uses the TMPFILE environment variable to decide where to create the temporary file.  If TMPFILE is not  set  or  is  set	to
       something unusable (e.g.  too long), pm_tmpfile() falls back to the value of the standard C library symbol P_tmpdir, just like tmpfile().

       Unlike  tmpfile(),  pm_tmpfile()  never returns NULL.  If it fails, it issues a message to Standard Error and aborts the program, like most
       libnetpbm routines do.

       If you need to refer to the temporary file by name, use pm_make_tmpfile() instead.

HISTORY

       pm_tmpfile() was introduced in Netpbm 10.20 (January 2004).

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
