Enumeration Type Documentation

Possible packet types used by KdSendPacket()/KdReceivePacket().
- Enumerator:
-
KdPacketType3 KdPacketAcknowledge Sent when a data packet was successfully received. KdPacketRetryRequest Sent when a corrupted data packet is received (or it cannot be processed now). KdPacketResynchronize Sent by WinDBG to resynchronize target and by target to acknowledge resync. KdPacketType7 KdCheckForAnyPacket Not a packet type. When specified to KdReceivePacket(), it checks whether any data is available on COM port. KdPacketType11
| enum _KD_RECV_CODE |

| __inout_opt PKD_BUFFER | FirstBuffer, | |||

| ) |
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.

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.
