=head1 DESCRIPTION
SSL_waiting_for_async() determines whether an SSL connection is currently
waiting for asynchronous operations to complete (see the SSL_MODE_ASYNC mode in
L<SSL_CTX_set_mode(3)>).
waiting for asynchronous operations to complete (see the B<SSL_MODE_ASYNC> mode
in L<SSL_CTX_set_mode(3)>).
SSL_get_all_async_fds() returns a list of file descriptor which can be used in a
call to select() or poll() to determine whether the current asynchronous
operation has completed or not. A completed operation will result in data
appearing as "read ready" on the file descriptor (no actual data should be read
from the file descriptor). This function should only be called if the SSL object
is currently waiting for asynchronous work to complete (i.e.
SSL_ERROR_WANT_ASYNC has been received - see L<SSL_get_error(3)>). Typically the
list will only contain one file descriptor. However if multiple asynchronous
from the file descriptor). This function should only be called if the B<SSL>
object is currently waiting for asynchronous work to complete (i.e.
B<SSL_ERROR_WANT_ASYNC> has been received - see L<SSL_get_error(3)>). Typically
the list will only contain one file descriptor. However if multiple asynchronous
capable engines are in use then more than one is possible. The number of file
descriptors returned is stored in B<*numfds> and the file descriptors themselves
are in B<*fds>. The B<fds> parameter may be NULL in which case no file
descriptors are returned but B<*numfds> is still populated. It is the callers
responsibility to ensure sufficient memory is allocated at B<*fds> so typically
this function is called twice (once with a NULL B<fds> parameter and once
descriptors returned is stored in I<*numfds> and the file descriptors themselves
are in I<*fds>. The I<fds> parameter may be NULL in which case no file
descriptors are returned but I<*numfds> is still populated. It is the callers
responsibility to ensure sufficient memory is allocated at I<*fds> so typically
this function is called twice (once with a NULL I<fds> parameter and once
without).
SSL_get_changed_async_fds() returns a list of the asynchronous file descriptors
that have been added and a list that have been deleted since the last
SSL_ERROR_WANT_ASYNC was received (or since the SSL object was created if no
SSL_ERROR_WANT_ASYNC has been received). Similar to SSL_get_all_async_fds() it
is the callers responsibility to ensure that B<*addfd> and B<*delfd> have
B<SSL_ERROR_WANT_ASYNC> was received (or since the B<SSL> object was created if
no B<SSL_ERROR_WANT_ASYNC> has been received). Similar to SSL_get_all_async_fds()
it is the callers responsibility to ensure that I<*addfd> and I<*delfd> have
sufficient memory allocated, although they may be NULL. The number of added fds
and the number of deleted fds are stored in B<*numaddfds> and B<*numdelfds>
and the number of deleted fds are stored in I<*numaddfds> and I<*numdelfds>
respectively.
