Data are received in blocks from the peer. Therefore data can be buffered

\&\fISSL_pending()\fR takes into account only bytes from the \s-1TLS/SSL\s0 record

that is currently being processed (if any). If the \fB\s-1SSL\s0\fR object's

|
\&\fIread_ahead\fR flag is set, additional protocol bytes may have been

read containing more \s-1TLS/SSL\s0 records; these are ignored by

|
\&\fISSL_pending()\fR.
