4.2.2. RspPacket class

4.2.2. `RspPacket` class

The RSP packet cannot be represented as a simple string, since binary packets may contain null (string terminator) characters. Instead the packet is represented as a character buffer and separate length field. However by convention the character buffer is also null-terminated, allowing non-binary packets to be printed out for debugging purposes. The public interface to this class is as follows:

RspPacket. The constructor takes a single integer argument, the size of the data buffer to allocate. It allocates that buffer and stores the record of its size.
~RspPacket. The destructor deletes the allocated data buffer.
data. A pointer to the data buffer.
packStr. Takes a string constant as argument and packs it into the data buffer, setting the length field to the length of the string.

getBufSize, getLen and setLen. Accessor functions to get the size of the data buffer and to get and set the length of the data currently stored there.

	Note
	Although by convention all data is stored null-terminated in the buffer, this null-termination is a convenience for debugging the GDB server and does not form part of the data. The length does not include this null-termination character.
