SSL_pending(3SSL) OpenSSL SSL_pending(3SSL)
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.
