Typedef Documentation

typedef struct picture_fifo_t picture_fifo_t

Picture fifo handle.

It is thread safe (push/pop).

Function Documentation

void picture_fifo_Delete

(

picture_fifo_t *

)

It destroys a fifo created by picture_fifo_New.

All pictures inside the fifo will be released by picture_Release.

void picture_fifo_Flush	(	picture_fifo_t *	,
		mtime_t	date,
		bool	flush_before
	)

It release all picture inside the fifo that have a lower or equal date if flush_before or higher or equal to if not flush_before than the given one.

All pictures inside the fifo will be released by picture_Release.

void picture_fifo_OffsetDate	(	picture_fifo_t *	,

picture_t* picture_fifo_Peek

(

picture_fifo_t *

)

It returns the first picture_t pointer from the fifo but does not remove it.

The picture returned has been hold for you so you must call picture_Release on it.

If the fifo is empty, it return NULL without waiting.
