void __stdcall DllEntryPoint

Definition at line 29 of file kdvm.cpp.

Here is the call graph for this function:

void HalInitSystem	(	void *	,
		void *
	)

NTSTATUS __stdcall KdDebuggerInitialize0

(

PVOID

lpLoaderParameterBlock

)

Performs initial KD extension DLL initialization.

Definition at line 338 of file kdvm.cpp.

Here is the call graph for this function:

KD_RECV_CODE __stdcall KdReceivePacket	(	__in ULONG	PacketType,
		__inout_opt PKD_BUFFER	FirstBuffer,
		__inout_opt PKD_BUFFER	SecondBuffer,
		__out_opt PULONG	PayloadBytes,
		__inout_opt PKD_CONTEXT	KdContext
	)

Called by kernel to receive a packet of a specified type.

This function is called by Windows kernel to receive a debug packet of a particular type.

Parameters:

	PacketType	Specifies the type of packet to receive. If KdCheckForAnyPacket is specified, the function checks whether any data is available (was sent by debugger, but not yet received) and returns KD_RECV_CODE_OK or KD_RECV_CODE_TIMEOUT respectively without performing any other action.
	FirstBuffer	Specifies the buffer where the first KD_BUFFER::MaxLength bytes of a packet are stored
	SecondBuffer	Specifies the buffer where the rest data of the packet is stored.
	PayloadBytes	Points to an ULONG value receiving the number of bytes written to SecondBuffer
	KdContext	Points to a KD_CONTEXT variable storing global packet layer context. If debugger requests stopping the execution, the KD_CONTEXT::BreakInRequested is set to TRUE.

Definition at line 358 of file kdvm.cpp.

Here is the call graph for this function:

VOID __stdcall KdSendPacket	(	__in ULONG	PacketType,
		__in PKD_BUFFER	FirstBuffer,
		__in_opt PKD_BUFFER	SecondBuffer,
		__inout PKD_CONTEXT	KdContext
	)

Called by kernel to send a debug packet.

This function is called by Windows kernel to send a debug packet.

Parameters:

	PacketType	Specifies the packet type to send.
	FirstBuffer	Specifies the first part of the packet body.
	SecondBuffer	Specifies the second part of the packet body.
	KdContext	Points to a KD_CONTEXT variable storing global packet layer context. KD_CONTEXT::RetryCount is used by original KDCOM.DLL implementation.

Remarks:

Note that the packet itself contains no information about sizes of FirstBuffer and SecondBuffer, its body just contains both buffer contens placed one after another.
