pm_make_tmpfile_fd() - create a temporary named file

       This library function is part of Netpbm(1).

       pm_make_tmpfile_fd() is analogous to pm_make_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 don't need to access the file by name, use pm_tmpfile_fd() instead, because  it's  cleaner.   With
       pm_tmpfile_fd(),  the  operating system always deletes the temporary file when your program exits, if the
       program failed to clean up after itself.

       This  simple  example  creates  a  temporary  file,  writes  "hello world" to it, then writes some search
       patterns to it, then uses it as input to grep:

       #include <netpbm/pm.h>

       int fd;
       const char * myfilename;

       pm_make_tmpfile_fd(&fdP, &myfilename);

       write(fd, "^account:\\s.*\n", 16);
       fprintf(fd, "^name:\\s.*\n", 13);

       close(fd);

       asprintfN(&grepCommand, "grep --file='%s' /tmp/infile >/tmp/outfile");

       system(grepCommand);

       strfree(grepCommand);

       unlink(myfilename);

       strfree(myfilename);

pm_tmpfile() was introduced in Netpbm 10.42 (March 2008).
