5 SSL_pending - obtain number of readable bytes buffered in an SSL object
9 #include <openssl/ssl.h>
11 int SSL_pending(const SSL *ssl);
15 SSL_pending() returns the number of bytes which are available inside
16 B<ssl> for immediate read.
20 Data are received in blocks from the peer. Therefore data can be buffered
21 inside B<ssl> and are ready for immediate retrieval with
22 L<SSL_read(3)|SSL_read(3)>.
26 The number of bytes pending is returned.
30 SSL_pending() takes into account only bytes from the TLS/SSL record
31 that is currently being processed (if any). If the B<SSL> object's
32 I<read_ahead> flag is set, additional protocol bytes may have been
33 read containing more TLS/SSL records; these are ignored by
36 Up to OpenSSL 0.9.6, SSL_pending() does not check if the record type
37 of pending data is application data.
