◆ KdSystemDebugControl()

NTSTATUS NTAPI KdSystemDebugControl ( _In_ SYSDBG_COMMAND  Command,
_In_reads_bytes_(InputBufferLength) PVOID  InputBuffer,
_In_ ULONG  InputBufferLength,
_Out_writes_bytes_(OutputBufferLength) PVOID  OutputBuffer,
_In_ ULONG  OutputBufferLength,
_Out_opt_ PULONG  ReturnLength,
_In_ KPROCESSOR_MODE  PreviousMode 
)

Perform various queries to the kernel debugger.

Parameters
[in]CommandA SYSDBG_COMMAND value describing the kernel debugger command to perform.
[in]InputBufferPointer to a user-provided input command-specific buffer, whose length is given by InputBufferLength.
[in]InputBufferLengthThe size (in bytes) of the buffer pointed by InputBuffer.
[out]OutputBufferPointer to a user-provided command-specific output buffer, whose length is given by OutputBufferLength.
[in]OutputBufferLengthThe size (in bytes) of the buffer pointed by OutputBuffer.
[out]ReturnLengthOptional pointer to a ULONG variable that receives the actual length of data written written in the output buffer. It is always zero, except for the live dump commands where an actual non-zero length is returned.
[in]PreviousModeThe processor mode (KernelMode or UserMode) in which the command is being executed.
Returns
STATUS_SUCCESS in case of success, or a proper error code otherwise.
Remarks
  • This is a kernel-mode function, accessible only by kernel-mode drivers.

◆ NtSystemDebugControl()

NTSYSCALLAPI NTSTATUS NTAPI NtSystemDebugControl ( _In_ SYSDBG_COMMAND  Command,
_In_reads_bytes_(InputBufferLength) PVOID  InputBuffer,
_In_ ULONG  InputBufferLength,
_Out_writes_bytes_(OutputBufferLength) PVOID  OutputBuffer,
_In_ ULONG  OutputBufferLength,
_Out_opt_ PULONG  ReturnLength 
)

Perform various queries to the kernel debugger.

Parameters
[in]CommandA SYSDBG_COMMAND value describing the kernel debugger command to perform.
[in]InputBufferPointer to a user-provided input command-specific buffer, whose length is given by InputBufferLength.
[in]InputBufferLengthThe size (in bytes) of the buffer pointed by InputBuffer.
[out]OutputBufferPointer to a user-provided command-specific output buffer, whose length is given by OutputBufferLength.
[in]OutputBufferLengthThe size (in bytes) of the buffer pointed by OutputBuffer.
[out]ReturnLengthOptional pointer to a ULONG variable that receives the actual length of data written written in the output buffer. It is always zero, except for the live dump commands where an actual non-zero length is returned.
Returns
STATUS_SUCCESS in case of success, or a proper error code otherwise.
Remarks
  • The caller must have SeDebugPrivilege, otherwise the function fails with STATUS_ACCESS_DENIED.
  • Only the live dump commands: SysDbgGetTriageDump, and SysDbgGetLiveKernelDump (Win8.1+) are available even if the debugger is disabled or absent.

  • The following system-critical commands are not accessible anymore for user-mode usage with this API on NT 5.2+ (Windows 2003 SP1 and later) systems:

    SysDbgQueryVersion, SysDbgReadVirtual and SysDbgWriteVirtual, SysDbgReadPhysical and SysDbgWritePhysical, SysDbgReadControlSpace and SysDbgWriteControlSpace, SysDbgReadIoSpace and SysDbgWriteIoSpace, SysDbgReadMsr and SysDbgWriteMsr, SysDbgReadBusData and SysDbgWriteBusData, SysDbgCheckLowMemory.

    For these, NtSystemDebugControl() will return STATUS_NOT_IMPLEMENTED. They are now available from kernel-mode only with KdSystemDebugControl().
