Detailed Description

Internal API for vchiq_arm MMAL client.

Typedef Documentation

Hold the context required when sending a buffer to the copro.

MMAL_STATUS_T mmal_vc_send_message	(	MMAL_CLIENT_T *	client,
		mmal_worker_msg_header *	msg_header,
		size_t	size,
		uint8_t *	data,
		size_t	data_size,
		uint32_t	msgid
	)

Send a message and do not wait for a reply.

Note:: This function should only be called from within a mmal component, so vchiq_use/release_service calls aren't required (dealt with at higher level).

Parameters:

client	client to send message for
msg_header	message header to send
size	length of message, including header
msgid	message id

MMAL_STATUS_T mmal_vc_sendwait_message	(	struct MMAL_CLIENT_T *	client,
		mmal_worker_msg_header *	msg_header,
		size_t	size,
		uint32_t	msgid,
		void *	dest,
		size_t *	destlen,
		MMAL_BOOL_T	send_dummy_bulk
	)

Send a message and wait for a reply.

Parameters:

client	client to send message for
msg_header	message vchiq_header to send
size	length of message, including header
msgid	message id
dest	destination for reply
destlen	size of destination, updated with actual length
send_dummy_bulk	whether to send a dummy bulk transfer
