tor_get_prfiledesc_byte_counts()

int tor_get_prfiledesc_byte_counts	(	PRFileDesc *	fd,
		uint64_t *	n_read_out,
		uint64_t *	n_written_out
	)

Given a PRFileDesc returned by tor_wrap_prfiledesc_with_byte_counter(), or another PRFileDesc wrapping that PRFileDesc, set the provided pointers to the number of bytes read and written on the descriptor since it was created.

Return 0 on success, -1 on failure.
