Function Documentation

MSTicker* ms_ticker_new

(

void

)

Create a ticker that will be used to start and stop a graph.

Returns: MSTicker * if successfull, NULL otherwise.

void ms_ticker_set_name	(	MSTicker *	ticker,
		const char *	name
	)

Set a name to the ticker (used for logging)

int ms_ticker_attach	(	MSTicker *	ticker,
		MSFilter *	f
	)

Attach a chain of filters to a ticker. The processing chain will be executed until ms_ticker_detach will be called.

Parameters:

ticker	A MSTicker object.
f	A MSFilter object.

Returns: 0 if successfull, -1 otherwise.

int ms_ticker_detach	(	MSTicker *	ticker,
		MSFilter *	f
	)

Dettach a chain of filters to a ticker. The processing chain will no more be executed.

Parameters:

ticker	A MSTicker object.
f	A MSFilter object.

Returns: 0 if successfull, -1 otherwise.

void ms_ticker_destroy

(

MSTicker *

ticker

)

Destroy a ticker.

Parameters:

ticker

A MSTicker object.

void ms_ticker_set_time_func	(	MSTicker *	ticker,
		MSTickerTimeFunc	func,
		void *	user_data
	)

Override MSTicker's time function. This can be used to control the ticker from an external time provider, for example the clock of a sound card.

Parameters:

ticker	A MSTicker object.
func	A replacement method for calculating "current time"
user_data	Any pointer to user private data.

void ms_ticker_print_graphs

(

MSTicker *

ticker

)

Print on stdout all filters of a ticker. (INTERNAL: DO NOT USE)

Parameters:

ticker

A MSTicker object.
