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

NAME
       pm_tmpfile_fd() - create a temporary unnamed file

SYNOPSIS
       #include <netpbm/pm.h>

       FILE *
       pm_tmpfile_fd(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>

       int fd;

       fd = pm_tmpfile();

       write(fd, 'hello world
', 17);

       lseek(fd, 0, SEEK_SET);

       read(fd, buffer, sizeof(buffer));

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

       close(fd);

DESCRIPTION
       This library function is part of Netpbm(1)

       pm_tmpfile_fd()	is  analogous  to pm_tmpfile()(1) that it opens the file as a low level file, as open() would, rather than as a stream, as
       fopen() would.

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

HISTORY
       pm_tmpfile() was introduced in Netpbm 10.42 (March 2008).
