Detailed Description

TCP sound-io library's interface to the framework callbacks.

Constructor & Destructor Documentation

io_asterisk_fwcb_t()

io_asterisk_fwcb_t::io_asterisk_fwcb_t	(	IOProcessEvent_t	proc_event,
		void *	proc_handle,
		IOStartedEvent_t	start_event,
		void *	start_handle,
		IOStoppedEvent_t	stop_event,
		void *	stop_handle
	)

Constructor stores framework handles and initializes error numbers to 0.

~io_asterisk_fwcb_t()

virtual io_asterisk_fwcb_t::~io_asterisk_fwcb_t ( )

inlinevirtual

Do-nothing destructor.

Member Function Documentation

start()

void io_asterisk_fwcb_t::start ( )

virtual

Call the framework's start callback.

process()

int io_asterisk_fwcb_t::process ( mha_wave_t *  sIn, mha_wave_t *&  sOut  )

virtual

Call the frameworks processing callback.

Parameters

sIn	The input sound data just received from TCP.
sOut	A pointer to output sound data. Will point to the output sound data storage when the callback finishes.

Returns

Status, an error number from the signal processing callback. If this is != 0, then the connection should be closed.

set_errnos()

void io_asterisk_fwcb_t::set_errnos ( int  proc_err, int  io_err  )

virtual

Save error numbers to use during.

See also

stop

Parameters

proc_err

The error number from the

See also

process callback.

Parameters

io_err

The error number from the io library itself.

stop()

void io_asterisk_fwcb_t::stop ( )

virtual

Call the frameworks stop callback.

Uses the error numbers set previously with

See also

set_errnos.

Member Data Documentation

proc_event

IOProcessEvent_t io_asterisk_fwcb_t::proc_event

private

Pointer to signal processing callback function.

start_event

IOStartedEvent_t io_asterisk_fwcb_t::start_event

private

Pointer to start notification callback function.

Called when a new TCP connection is established or the user issues the start command while there is a connection.

stop_event

IOStoppedEvent_t io_asterisk_fwcb_t::stop_event

private

Pointer to stop notification callback function.

Called when the connection is closed.

proc_handle

void* io_asterisk_fwcb_t::proc_handle

private

Handles belonging to framework.

start_handle

void * io_asterisk_fwcb_t::start_handle

private

stop_handle

void * io_asterisk_fwcb_t::stop_handle

private

proc_err

int io_asterisk_fwcb_t::proc_err

private

Errors from the processing callback and from the TCP IO itself are stored here before closing Network handles.

MHAIOTCP is notified by the server when the connection has been taken down, and calls

See also

stop from that callback. Within stop, these error numbers are read again and transmitted to the framework.

io_err

int io_asterisk_fwcb_t::io_err

private
