NAME
SSL_pending - obtain number of readable bytes buffered in an SSL object
SYNOPSIS
#include <openssl/ssl.h>
int SSL_pending(const 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.
BUGS
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 (see
SSL_CTX_set_read_ahead(3)), 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.
