MMAL_DRIVER_BUFFER_T* mmal_buffer_header_driver_data ( MMAL_BUFFER_HEADER_T * )

Return a pointer to the area reserved for the driver.

MMAL_BUFFER_HEADER_T* mmal_buffer_header_initialise	(	void *	mem,
		unsigned int	length
	)

MMAL_BUFFER_HEADER_T* mmal_buffer_header_reference ( MMAL_BUFFER_HEADER_T * header )

Return a pointer to a referenced buffer header. It is the caller's responsibility to ensure that the reference is still valid when using it.

unsigned int mmal_buffer_header_size ( MMAL_BUFFER_HEADER_T * header )

Get the size in bytes of a fully initialised MMAL_BUFFER_HEADER_T
