"readable". Once resumed the engine should clear the wake signal on the wait
file descriptor.
As well as a file descriptor, user code may also be notified via a callback. The
callback and data pointers are stored within the ASYNC_WAIT_CTX along with an
additional status field that can be used for the notification of retries from an
engine. This additional method can be used when the user thinks that a file
descriptor is too costly in terms of CPU cycles or in some context where a file
descriptor is not appropriate.
ASYNC_WAIT_CTX_set_callback() sets the callback and the callback argument. The
callback will be called to notify user code when an engine completes a
cryptography operation. It is a requirement that the callback function is small
and non-blocking as it will be run in the context of a polling mechanism or an
interrupt.
ASYNC_WAIT_CTX_get_callback() returns the callback set in the ASYNC_WAIT_CTX
structure.
ASYNC_WAIT_CTX_set_status() allows an engine to set the current engine status.
The possible status values are the following:
ASYNC_STATUS_UNSUPPORTED: The engine does not support the callback mechanism.
This is the default value. The engine must call ASYNC_WAIT_CTX_set_status() to
set the status to some value other than ASYNC_STATUS_UNSUPPORTED if it intends
to enable the callback mechanism.
ASYNC_STATUS_ERR: The engine has a fatal problem with this request. The user
code should clean up this session.
ASYNC_STATUS_OK: The request has been successfully submitted.
ASYNC_STATUS_EAGAIN: The engine has some problem which will be recovered soon,
such as a buffer is full, so user code should resume the job.
ASYNC_WAIT_CTX_get_status() allows user code to obtain the current status value.
If the status is any value other than ASYNC_STATUS_OK then the user code should
not expect to receive a callback from the engine even if one has been set.
An example of the usage of the callback method might be the following. User
code would initiate cryptographic operations, and the engine code would dispatch
this operation to hardware, and if the dispatch is successful, then the engine
code would call ASYNC_pause_job() to return control to the user code. After
that, user code can perform other tasks. When the hardware completes the
operation, normally it is detected by a polling function or an interrupt, as the
user code set a callback by calling ASYNC_WAIT_CTX_set_callback() previously,
then the registered callback will be called.

ASYNC_get_wait_ctx() can be used to get a pointer to the ASYNC_WAIT_CTX
for the B<job>. ASYNC_WAIT_CTXs can have a "wait" file descriptor associated
with them. Applications can wait for the file descriptor to be ready for "read"
using a system function call such as select or poll (being ready for "read"
indicates that the job should be resumed). If no file descriptor is made
available then an application will have to periodically "poll" the job by
attempting to restart it to see if it is ready to continue.
for the B<job>. ASYNC_WAIT_CTXs contain two different ways to notify
applications that a job is ready to be resumed. One is a "wait" file
descriptor, and the other is a "callback" mechanism.
An example of typical usage might be an async capable engine. User code would
initiate cryptographic operations. The engine would initiate those operations
asynchronously and then call L<ASYNC_WAIT_CTX_set_wait_fd(3)> followed by
ASYNC_pause_job() to return control to the user code. The user code can then
perform other tasks or wait for the job to be ready by calling "select" or other
similar function on the wait file descriptor. The engine can signal to the user
code that the job should be resumed by making the wait file descriptor
"readable". Once resumed the engine should clear the wake signal on the wait
file descriptor.
The "wait" file descriptor associated with ASYNC_WAIT_CTX is used for
applications to wait for the file descriptor to be ready for "read" using a
system function call such as select or poll (being ready for "read" indicates
that the job should be resumed). If no file descriptor is made available then
an application will have to periodically "poll" the job by attempting to restart
it to see if it is ready to continue.
ASYNC_WAIT_CTXs also have a "callback" mechanism to notify applications. The
callback is set by an application, and it will be automatically called when an
engine completes a cryptography operation, so that the application can resume
the paused work flow without polling. An engine could be written to look whether
the callback has been set. If it has then it would use the callback mechanism
in preference to the file descriptor notifications. If a callback is not set
then the engine may use file descriptor based notifications. Please note that
not all engines may support the callback mechanism, so the callback may not be
used even if it has been set. See ASYNC_WAIT_CTX_new() for more details.
The ASYNC_block_pause() function will prevent the currently active job from
pausing. The block will remain in place until a subsequent call to

typedef int (*SSL_async_callback_fn)(SSL *s, void *arg);

int SSL_get_async_status(SSL *s, int *status);
=head1 DESCRIPTION
SSL_CTX_set_async_callback() sets an asynchronous callback function. All SSL
objects generated based on this SSL_CTX will get this callback. If an engine
supports the callback mechanism, it will be automatically called if
SSL_MODE_ASYNC has been set and an asynchronous capable engine completes a
cryptography operation to notify the application to resume the paused work flow.
SSL_CTX_set_async_callback_arg() sets the callback argument.
SSL_set_async_callback() allows an application to set a callback in an
asynchronous SSL object, so that when an engine completes a cryptography
operation, the callback will be called to notify the application to resume the
paused work flow.
SSL_set_async_callback_arg() sets an argument for the SSL object when the above
callback is called.
SSL_get_async_status() returns the engine status. This function facilitates the
communication from the engine to the application. During an SSL session,
cryptographic operations are dispatched to an engine. The engine status is very
useful for an application to know if the operation has been successfully
dispatched. If the engine does not support this additional callback method,
"ASYNC_STATUS_UNSUPPORTED" will be returned. See ASYNC_WAIT_CTX_set_status() for
a description of all of the status values.
An example of the above functions would be the following.
1. Application sets the async callback and callback data on an SSL connection
by calling SSL_set_async_callback().
2. Application sets SSL_MODE_ASYNC and makes an asynchronous SSL call
3. OpenSSL submits the asynchronous request to the engine. If a retry occurs at
this point then the status within the ASYNC_WAIT_CTX would be set and the async
callback function would be called (goto Step 7).
4. The OpenSSL engine pauses the current job and returns, so that the
application can continue processing other connections.
5. At a future point in time (probably via a polling mechanism or via an
interrupt) the engine will become aware that the asynchronous request has
finished processing.
6. The engine will call the application's callback passing the callback data as
a parameter.
7. The callback function should then run. Note: it is a requirement that the
callback function is small and non-blocking as it will be run in the context of
a polling mechanism or an interrupt.
8. It is the application's responsibility via the callback function to schedule
recalling the OpenSSL asynchronous function and to continue processing.
9. The callback function has the option to check the status returned via
SSL_get_async_status() to determine whether a retry happened instead of the
request being submitted, allowing different processing if required.
