SYNOPSIS

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

EXAMPLE

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

DESCRIPTION

46       This library function is part of Netpbm(1).
47
48       pm_make_tmpfile_fd()  is analogous to pm_make_tmpfile()(1).Theonly dif‐
49       ference is that it opens the file as a low level file, as open() would,
50       rather than as a stream, as fopen() would.
51
52       If  you  don't  need  to  access  the file by name, use pm_tmpfile_fd()
53       instead, because it's cleaner.   With  pm_tmpfile_fd(),  the  operating
54       system  always  deletes  the temporary file when your program exits, if
55       the program failed to clean up after itself.
