Therefore data can be buffered +inside B<ssl> and are ready for immediate retrieval with +L<SSL_read(3)|SSL_read(3)>. + +=head1 RETURN VALUES + +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. + +=head1 SEE ALSO + +L<SSL_read(3)|SSL_read(3)>, L<ssl(3)|ssl(3)> + +=cut |
