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 world0, 17);
lseek(fd, 0, SEEK_SET);
read(fd, buffer, sizeof(buffer));
fprintf(STDOUT, temp file contains %s0, buffer);
close(fd);
DESCRIPTION
This library function is part of Netpbm(1)
pm_tmpfile_fd() is analogous to
pm_tmpfile()(3)
.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).
