SYNOPSIS

10       #include <netpbm/pm.h>
11
12       pm_make_tmpfile(int *         fdP,
13                       const char ** filenameP);

EXAMPLE

18       This  simple  example creates a temporary file, writes "hello world" to
19       it, then writes some search patterns to it, then uses it  as  input  to
20       grep:
21
22       #include <netpbm/pm.h>
23
24       int fd;
25       const char * myfilename;
26
27       pm_make_tmpfile_fd(&fdP, &myfilename);
28
29       write(fd, "^account:\\s.*\n", 16);
30       fprintf(fd, "^name:\\s.*\n", 13);
31
32       close(fd);
33
34       asprintfN(&grepCommand, "grep --file='%s' /tmp/infile >/tmp/outfile");
35
36       system(grepCommand);
37
38       strfree(grepCommand);
39
40       unlink(myfilename);
41
42       strfree(myfilename);

DESCRIPTION

48       This library function is part of Netpbm(1).
49
50       pm_make_tmpfile_fd()  is  analogous  to pm_make_tmpfile()(1).  The only
51       difference is that it opens the file as a low  level  file,  as  open()
52       would, rather than as a stream, as fopen() would.
53
54       If  you  don't need to access the file by name, use pm_tmpfile_fd() in‐
55       stead, because it's cleaner.  With pm_tmpfile_fd(), the operating  sys‐
56       tem  always  deletes the temporary file when your program exits, if the
57       program failed to clean up after itself.
