<a name="index-in_002dprocess-agent-protocol"></a>

<p>The in-process agent is able to communicate with both <small>GDB</small> and
GDBserver (see <a href="In_002dProcess-Agent.html#In_002dProcess-Agent">In-Process Agent</a>).  This section documents the protocol
used for communications between <small>GDB</small> or GDBserver and the IPA.
In general, <small>GDB</small> or GDBserver sends commands
(see <a href="IPA-Protocol-Commands.html#IPA-Protocol-Commands">IPA Protocol Commands</a>) and data to in-process agent, and then
in-process agent replies back with the return result of the command, or
some other information.  The data sent to in-process agent is composed
of primitive data types, such as 4-byte or 8-byte type, and composite
types, which are called objects (see <a href="IPA-Protocol-Objects.html#IPA-Protocol-Objects">IPA Protocol Objects</a>).
