NTSTATUS KdDisableDebugger();
View the official Windows Driver Kit DDI referenceNo description available.
The KdDisableDebugger routine disables the kernel debugger.
KdDisableDebugger returns STATUS_SUCCESS if the kernel debugger was successfully disabled. Otherwise, the return value can be one of the following error status codes:
STATUS_ACCESS_DENIED
STATUS_DEBUGGER_INACTIVE
If the operating system was booted with no debug controls, KdDisableDebugger returns STATUS_DEBUGGER_INACTIVE.
If the kernel debugger is blocked (that is, the KdBlockEnable system variable is set to a value other than FALSE), KdDisableDebugger returns STATUS_ACCESS_DENIED.
After a caller calls KdDisableDebugger to disable the kernel debugger, the caller can call the KdEnableDebugger routine to re-enable the kernel debugger.
