the output yourself in some meaningful fashion.

Title "SSL_pending 3"
SSL_pending 3 "0.9.7" "2003-01-13" "OpenSSL"
C "NAME"
SSL_pending - obtain number of readable bytes buffered in an \s-1SSL\s0 object
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1
#include <openssl/ssl.h>
.Ve
.Vb 1
int SSL_pending(SSL *ssl);
.Ve
"DESCRIPTION"
Header "DESCRIPTION" \fISSL_pending() returns the number of bytes which are available inside
\fBssl for immediate read.
"NOTES"
Header "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"
Header "RETURN VALUES" The number of bytes pending is returned.
"BUGS"
Header "BUGS" \fISSL_pending() takes into account only bytes from the \s-1TLS/SSL\s0 record
that is currently being processed (if any). If the \s-1SSL\s0 object's
\fIread_ahead flag is set, additional protocol bytes may have been
read containing more \s-1TLS/SSL\s0 records; these are ignored by
\fISSL_pending().
Up to OpenSSL 0.9.6, SSL_pending() does not check if the record type of pending data is application data.
