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, 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.
