KdBreakPointWithStatus macro

The KdBreakPointWithStatus macro breaks into the kernel debugger and sends the value of Status to the debugger.

Syntax

void KdBreakPointWithStatus(
   s
);

Parameters

s

Specifies a ULONG value to be sent to the debugger (for example, a status code or an address).

Return Value

None

Remarks

KdBreakPointWithStatus is identical to the DbgBreakPointWithStatus routine in code that is compiled for a debug configuration. This routine has no effect if compiled in a release configuration.

On x86 computers, the Status parameter is stored in the eax register. On computers that have register calling conventions, Status is stored in the first argument register.

This routine raises an exception that is handled by the kernel debugger if one is installed; otherwise it is handled by the debug system. If a debugger is not connected to the system, the exception can be handled in the standard way.

In kernel mode, a break exception that is not handled will cause a bug check. You can, however, connect a kernel-mode debugger to a target computer that has stopped responding and has kernel debugging enabled. For more information, see Windows Debugging.
