.IX Header "NOTES"
|
|
Data are received in blocks from the peer. Therefore data can be buffered

inside \fBssl\fR and are ready for immediate retrieval with

|
|
\&\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.
|
|
.PP
|

Up to OpenSSL 0.9.6, \fISSL_pending()\fR does not check if the record type

of pending data is application data.
