pm_tmpfile_fd()

NAME

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.

pm_tmpfile_fd() is analogous to pm_tmpfile(). 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).
