BIO_get_close() returns the BIOs close flag.

BIO_pending(), BIO_ctrl_pending(), BIO_wpending() and BIO_ctrl_wpending()

return the number of pending characterers in the BIOs read and write buffers.

return the number of pending characters in the BIOs read and write buffers.

Not all BIOs support these calls. BIO_ctrl_pending() and BIO_ctrl_wpending()

return a size_t type and are functions, BIO_pending() and BIO_wpending() are

macros which call BIO_ctrl().

The lack of support for BIO_puts() and the non standard behavior of

BIO_gets() could be regarded as anomalous. It could be argued that BIO_gets()

BIO_f_ssl() returns the SSL BIO method. This is a filter BIO which

is a wrapper round the OpenSSL SSL routines adding a BIO "flavor" to

SSL I/O. 

I/O performed on an SSL BIO communicates using the SSL protocol with

least 512 bytes.

BIO_set_ssl_renegotiate_timeout() sets the renegotiate timeout to

B<seconds>. When the renegotiate timeout elapses the sesssion is

B<seconds>. When the renegotiate timeout elapses the session is

automatically renegotiated.

BIO_get_num_renegotiates() returns the total number of session

case where this happens is when SGC or step up occurs.

In OpenSSL 0.9.6 and later the SSL flag SSL_AUTO_RETRY can be

set to disable this behaviour. That is when this flag is set

an SSL BIO using a blocking transport will never request a

retry.

Some BIOs (such as memory BIOs) can be used immediately after calling

BIO_new(). Others (such as file BIOs) need some additional initialisation,

BIO_new(). Others (such as file BIOs) need some additional initialization,

and frequently a utility function exists to create and initialize such BIOs.

If BIO_free() is called on a BIO chain it will only free one BIO resulting
