     NAME
          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.
