Function Documentation

packCursorData()

void packCursorData	(	const RenderedCircleData *	cursor,
		char *	buffer )

Packs cursor data into a string buffer for transmission.

This function packs the x and y coordinates of the cursor into a comma-separated string.

Parameters

cursor	Pointer to the RenderedCircleData structure representing the cursor data.
buffer	Pointer to the buffer where the packed data will be stored.

packStateData()

void packStateData	(	const StateData *	stateData,
		char *	buffer )

Packs StateData struct into a byte buffer.

Parameters

stateData	Pointer to the StateData struct to pack.
buffer	Pointer to the byte buffer where packed data will be stored.

packTargetData()

void packTargetData	(	const RenderedCircleData *	target,
		uint8_t	targetIndex,
		char *	buffer )

Packs target data into a string buffer for transmission.

This function packs messages in the format "x,y,radius,render,targetIndex".

Parameters

target	Pointer to the RenderedCircleData structure representing the target data.
targetIndex	Index of the target.
buffer	Pointer to the buffer where the packed data will be stored.

unpackCursorData()

void unpackCursorData	(	RenderedCircleData *	cursor,
		const char *	buffer )

Unpacks cursor data from a received message and updates the cursor position.

This function assumes that the received message is in the format "x,y".

Parameters

cursor	Pointer to the RenderedCircleData structure representing the cursor.
buffer	Pointer to the buffer containing the received message.

unpackStateData()

void unpackStateData	(	StateData *	stateData,
		const char *	buffer )

Unpacks byte buffer into StateData struct.

Parameters

stateData	Pointer to the StateData struct to populate.
buffer	Pointer to the byte buffer containing packed data.

unpackTargetData()

void unpackTargetData	(	RenderedCircleData **	targets,
		const char *	buffer )

Unpacks target data from a received message and updates the targets array.

This function assumes that the received message is in the format "x,y,radius,render,targetIndex".

Parameters

targets	Array of pointers to RenderedCircleData structures representing the targets.
buffer	Pointer to the buffer containing the received message.
