Macro Definition Documentation

#define ipc_msg_copy_handle_from_reference	(		msg,
			handle
	)

Value:

(msg).num_copy_handles = 1; \
    (msg).copy_handles = handle;

#define ipc_msg_copy_handle_from_value	(		msg,
			handle
	)

Value:

(msg).num_copy_handles = 1; \
    (msg).copy_handles = &(handle);

#define ipc_msg_raw_data_from_reference	(		msg,
			ptr
	)

Value:

msg.raw_data_size = sizeof(*(ptr)); \
    msg.raw_data = (uint32_t*) (ptr);

#define ipc_msg_raw_data_from_value	(		msg,
			val
	)

Value:

msg.raw_data_size = sizeof(val); \
    msg.raw_data = (uint32_t*) (&(val));

#define ipc_msg_set_buffers	(		msg,
			obj_arr,
			ptr_arr
	)

Value:

ipc_buffer_t *(ptr_arr)[ARRAY_LENGTH(obj_arr)]; \
    for(size_t i = 0; i < ARRAY_LENGTH(obj_arr); i++) { \
        (ptr_arr)[i] = &(obj_arr)[i]; \
    } \
    (msg).num_buffers = ARRAY_LENGTH(obj_arr); \
    (msg).buffers = (ptr_arr);
