* bitset.h -- some simple bit vector set operations.

* don't need them right now.
*
* These functions represent sets as arrays of unsigned 32-bit
* integers allocated on the heap. The first entry contains the set
* cardinality (number of elements allowed), followed by one or more

typedef struct _jack_driver {

/* The _jack_driver structure fields are included at the beginning of
each driver-specific structure using the JACK_DRIVER_DECL macro,
which is defined below. The comments that follow describe each
common field.
The driver should set this to be the interval it expects to elapse
between returning from the `wait' function. if set to zero, it
implies that the driver does not expect regular periodic wakeups.

jack_time_t period_usecs;


The driver should set this within its "wait" function to indicate
the UST of the most recent determination that the engine cycle
should run. it should not be set if the "extra_fd" argument of
the wait function is set to a non-zero value.

jack_time_t last_wait_ust;


These are not used by the driver. They should not be written to or
modified in any way
void *handle;
struct _jack_internal_client *internal_client;

This should perform any cleanup associated with the driver. it will
be called when jack server process decides to get rid of the
driver. in some systems, it may not be called at all, so the driver
should never rely on a call to this. it can set it to NULL if
it has nothing do do.

void (*finish)(struct _jack_driver *);


The JACK engine will call this when it wishes to attach itself to
the driver. the engine will pass a pointer to itself, which the driver
may use in anyway it wishes to. the driver may assume that this
is the same engine object that will make `wait' calls until a
`detach' call is made.

JackDriverAttachFunction attach;


The JACK engine will call this when it is finished using a driver.

JackDriverDetachFunction detach;


The JACK engine will call this when it wants to wait until the
driver decides that its time to process some data. the driver returns
a count of the number of audioframes that can be processed.

it should set the variable pointed to by `status' as follows:

zero: the wait completed normally, processing may begin
negative: the wait failed, and recovery is not possible
positive: the wait failed, and the driver stopped itself.
a call to `start' will return the driver to
a correct and known state.

the driver should also fill out the `delayed_usecs' variable to
indicate any delay in its expected periodic execution. for example,
if it discovers that its return from poll(2) is later than it
expects it to be, it would place an estimate of the delay
in this variable. the engine will use this to decide if it
plans to continue execution.

JackDriverWaitFunction wait;


The JACK engine will call this to ask the driver to move
data from its inputs to its output port buffers. it should
return 0 to indicate successful completion, negative otherwise.
This function will always be called after the wait function (above).

JackDriverReadFunction read;


The JACK engine will call this to ask the driver to move
data from its input port buffers to its outputs. it should
return 0 to indicate successful completion, negative otherwise.
this function will always be called after the read function (above).

JackDriverWriteFunction write;


The JACK engine will call this after the wait function (above) has
been called, but for some reason the engine is unable to execute
a full "cycle". the driver should do whatever is necessary to
keep itself running correctly, but cannot reference ports
or other JACK data structures in any way.

JackDriverNullCycleFunction null_cycle;

The engine will call this when it plans to stop calling the `wait'
function for some period of time. the driver should take
appropriate steps to handle this (possibly no steps at all).
NOTE: the driver must silence its capture buffers (if any)
from within this function or the function that actually
implements the change in state.

JackDriverStopFunction stop;


The engine will call this to let the driver know that it plans
to start calling the `wait' function on a regular basis. the driver
should take any appropriate steps to handle this (possibly no steps
at all). NOTE: The driver may wish to silence its playback buffers
(if any) from within this function or the function that actually
implements the change in state.
JackDriverStartFunction start;

The engine will call this to let the driver know that some client
has requested a new buffer size. The stop function will be called
prior to this, and the start function after this one has returned.

JackDriverBufSizeFunction bufsize;
