- int SSL_pending(SSL *ssl);
+ int SSL_pending(const SSL *ssl);
=head1 DESCRIPTION
Data are received in blocks from the peer. Therefore data can be buffered
inside B<ssl> and are ready for immediate retrieval with
-L<SSL_read(3)|SSL_read(3)>.
+L<SSL_read(3)>.
=head1 RETURN VALUES
The number of bytes pending is returned.
-L<SSL_read(3)|SSL_read(3)>, L<ssl(3)|ssl(3)>
+=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 (see
+L<SSL_CTX_set_read_ahead(3)>), additional protocol
+bytes may have been read containing more TLS/SSL records; these are ignored by
+SSL_pending().
