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.
SEE ALSO
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.
