/*
* telldir.c -- Android compatibility hack because bionic doesn't

/*
* We're doing something evil, evil, evil, but there's no way around
* this because bionic doesn't implment telldir/seekdir, even though
* those interfaces are in POSIX (sob). Fortunately (unfortunately)
* Apportable decided to copy this structure into a commonly used NDK
* library, so it's unlikely the first field in this structure will
* change. See b/210372080 or bionic/libc/bionic/dirent.cpp and the
* comments before the definition of struct DIR in that file for more
* details.
*
* The real right answer is the telldir/seekdir functions that we're
* implementing here should be moved to bionic....
