% dirfd(3) Version 1.0 | Library Functions Manual

NAME

dirfd — get directory stream file descriptor

LIBRARY

libmega C library (-lmega)

SYNOPSIS

#include <dirent.h>

int dirfd(DIR *dirp);

DESCRIPTION

The function dirfd() returns the file descriptor associated with the directory stream dirp.

Not really sure why you'd want this as messing with the fd directly will cause all sorts of bad thimgs to happen, but the function is in the standard librarry, so here it is. You have been warned.

RETURN VALUE

Never succeeds as this implementation doesn't work that way, so -1 is always returned, and errno is set to indicate the error.

ERRORS

NAME() can fail with the following errors:

• ENOTSUP - this implementation does not associate a file descriptor with the directory stream.

NOTES

None.
