SSL_pending(3) OpenSSL 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);
DESCRIPTIONSSL_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.
BUGSSSL_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.
