gclib_revision_information()

gclib_result gclib_revision_information	(	gclib_handle	h,
		char *	rev_info,
		size_t	len )

Get revision information (^R^V) from controller.

Parameters

h	Handle to an open connection.
rev_info	Output buffer for revision information.
len	Size of output buffer.

Returns

• GCLIB_INVALID_ARGUMENT if handle is NULL.
• GCLIB_NOT_CONNECTED if not connected.
• GCLIB_BUFFER_TOO_SMALL if output does not fit in buffer.

gclib_serial_number()

gclib_result gclib_serial_number	(	gclib_handle	h,
		uint32_t *	serial_number )

Get serial number from controller.

Parameters

h	Handle to an open connection.
serial_number	Will be set to the serial number of the controller, or 0 on failure.

Returns

GCLIB_INTERNAL_ERROR if serial number could not be retrieved.

gclib_command()

gclib_result gclib_command	(	gclib_handle	h,
		const char *	command,
		char *	buf,
		size_t	len )

Issues a command to the controller and provides the response.

Note that a single command cannot be longer than 80 characters, similar to a program line.

Parameters

h	Handle to an open connection.
command	Command to be sent to the controller. Will be terminated with a carriage return.
buf	Output buffer for controller response.
len	Length of output buffer.

Returns

• GCLIB_TIMEOUT if no response is received from the controller.
• GCLIB_COMMAND_ERROR if the controller responds with ?
• `GCLIB_BUFFER_TOO_SMALL if the command response cannot fit in the provided buffer.
