#include <netpbm/pm.h> FILE * pm_tmpfile_fd(void);
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);
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.
pm_tmpfile() was introduced in Netpbm 10.42 (March 2008).
