NAME
SSL_pending — obtain number of readable bytes buffered in an SSL object
Synopsis
#include <openssl/ssl.h>
int
SSL_pending(SSL *ssl);
DESCRIPTION
SSL_pending() returns the number of bytes which are available
inside ssl for immediate read.
NOTES
Data are received in blocks from the peer. Therefore data
can be buffered inside ssl and are ready for immediate retrieval
with SSL_read(3).
RETURN VALUES
The number of bytes pending is returned.
Restrictions
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.
