SSL_PENDING(3) OpenSSL SSL_PENDING(3)
SSL_pending - obtain number of readable bytes buffered in an SSL object
#include <openssl/ssl.h> int SSL_pending(const SSL *ssl);
SSL_pending() returns the number of bytes which are avail- able 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 SSL_read(3).
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.
