SSL_pending - obtain number of readable bytes buffered in
       an SSL object


SYNOPSIS

        #include <openssl/ssl.h>

        int SSL_pending(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.
