1=pod 2 3=head1 NAME 4 5SSL_pending - obtain number of readable bytes buffered in an SSL object 6 7=head1 SYNOPSIS 8 9 #include <openssl/ssl.h> 10 11 int SSL_pending(const SSL *ssl); 12 13=head1 DESCRIPTION 14 15SSL_pending() returns the number of bytes which are available inside 16B<ssl> for immediate read. 17 18=head1 NOTES 19 20Data are received in blocks from the peer. Therefore data can be buffered 21inside B<ssl> and are ready for immediate retrieval with 22L<SSL_read(3)|SSL_read(3)>. 23 24=head1 RETURN VALUES 25 26The number of bytes pending is returned. 27 28=head1 BUGS 29 30SSL_pending() takes into account only bytes from the TLS/SSL record 31that is currently being processed (if any). If the B<SSL> object's 32I<read_ahead> flag is set (see 33L<SSL_CTX_set_read_ahead(3)|SSL_CTX_set_read_ahead(3)>), additional protocol 34bytes may have been read containing more TLS/SSL records; these are ignored by 35SSL_pending(). 36 37Up to OpenSSL 0.9.6, SSL_pending() does not check if the record type 38of pending data is application data. 39 40=head1 SEE ALSO 41 42L<SSL_read(3)|SSL_read(3)>, 43L<SSL_CTX_set_read_ahead(3)|SSL_CTX_set_read_ahead(3)>, L<ssl(3)|ssl(3)> 44 45=cut 46
