=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 (see |
|
L<SSL_CTX_set_read_ahead(3)|SSL_CTX_set_read_ahead(3)>), 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. |
