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).
