+=head1 NAME
+
+SSL_pending - obtain number of readable bytes buffered in an SSL object
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ int SSL_pending(const SSL *ssl);
+
+=head1 DESCRIPTION
+
+SSL_pending() returns the number of bytes which are available inside
+B<ssl> for immediate read.
+
+=head1 NOTES
+
+Data are received in blocks from the peer. Therefore data can be buffered
+inside B<ssl> and are ready for immediate retrieval with
+L<SSL_read(3)|SSL_read(3)>.
+
+=head1 RETURN VALUES
+
+The number of bytes pending is returned.
+
+=head1 BUGS
+
+SSL_pending() takes into account only bytes from the TLS/SSL record
+that is currently being processed (if any).  If the B<SSL> object's
+I<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.
