=head1 DESCRIPTION
The number of bytes pending is returned.
+=head1 BUGS
+
+SSL_pending() takes into account only bytes from the TLS/SSL record
+that is currently being processed (if any). If the B<SSL> object's
+I<read_ahead> flag is set, additional protocol bytes may have been
+read containing more TLS/SSL records; these are ignored by
+SSL_pending().
+
+Up to OpenSSL 0.9.6, SSL_pending() does not check if the record type
+of pending data is application data.
