dirfd − get directory stream file descriptor
#include
<sys/types.h>
#include <dirent.h>
int dirfd(DIR *dir);
The function dirfd() returns the file descriptor associated with the directory stream dir.
On error −1 is returned.
The prototype for dirfd is only available if _BSD_SOURCE or _SVID_SOURCE is defined (either explicitly, or implicitly, by not defining _POSIX_SOURCE or compiling with the -ansi flag).
This is a BSD extension, present in 4.3BSD-Reno, not in 4.2BSD. Present in libc5 (since 5.1.2) and in glibc2.
