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\n", 17);

       lseek(fd, 0, SEEK_SET);

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

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

       close(fd);

DESCRIPTION

       This library function is part of Netpbm(1).

       pm_tmpfile_fd() is analogous to pm_tmpfile()(1).  The only difference is 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).
