SSL_pending(3) OpenSSL SSL_pending(3)
SSL_pending - obtain number of readable bytes buffered in an SSL object
int SSL_pending(SSL *ssl);
SSL_pending() returns the number of bytes which are available inside
ssl for immediate read.
Data are received in blocks from the peer. Therefore data can be
buffered inside ssl and are ready for immediate retrieval with
The number of bytes pending is returned.
SSL_pending() takes into account only bytes from the TLS/SSL record
that is currently being processed (if any). If the SSL object's
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.
