SSL_pending(3)SSL_pending(3)NAMESSL_pending - Obtain number of readable bytes buffered in an SSL object
SYNOPSIS
#include <openssl/ssl.h>
int SSL_pending(
SSL *ssl );
DESCRIPTION
The SSL_pending() function returns the number of bytes which are availā
able 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 the
SSL_read() function.
RESTRICTIONS
The SSL_pending() function takes into account only bytes from the
TLS/SSL record that is 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 the SSL_pending()
function.
Up to OpenSSL 0.9.6, the SSL_pending() function does not check if the
record type of pending data is application data.
RETURN VALUES
The number of bytes pending is returned.
