DEBUG_EVENT

The DEBUG_EVENT structure describes a debugging event.

Members

dwDebugEventCode

Specifies a debugging event code that identifies the type of debugging event. This parameter can be one of the following values:

Value		Meaning
EXCEPTION_DEBUG_EVENT
	Reports an exception debugging event. The value of u.Exception specifies an EXCEPTION_DEBUG_INFO structure.
CREATE_THREAD_DEBUG_EVENT
	Reports a create-thread debugging event. The value of u.CreateThread specifies a CREATE_THREAD_DEBUG_INFO structure.
CREATE_PROCESS_DEBUG_EVENT
	Reports a create-process debugging event. The value of u.CreateProcessInfo specifies a CREATE_PROCESS_DEBUG_INFO structure.
EXIT_THREAD_DEBUG_EVENT
	Reports an exit-thread debugging event. The value of u.ExitThread specifies an EXIT_THREAD_DEBUG_INFO structure.
EXIT_PROCESS_DEBUG_EVENT
	Reports an exit-process debugging event. The value of u.ExitProcess specifies an EXIT_PROCESS_DEBUG_INFO structure.
LOAD_DLL_DEBUG_EVENT
	Reports a load-dynamic-link-library (DLL) debugging event. The value of u.LoadDll specifies a LOAD_DLL_DEBUG_INFO structure.
UNLOAD_DLL_DEBUG_EVENT
	Reports an unload-DLL debugging event. The value of u.UnloadDll specifies an UNLOAD_DLL_DEBUG_INFO structure.
OUTPUT_DEBUG_STRING_EVENT
	Reports an output-debugging-string debugging event. The value of u.DebugString specifies an OUTPUT_DEBUG_STRING_INFO structure.
RIP_EVENT
	Reports a RIP-debugging event (system debugging error). The value of u.RipInfo specifies a RIP_INFO structure.

dwProcessId

Specifies the identifier of the process in which the debugging event occurred. A debugger uses this value to locate the debugger's per-process structure. These values are not necessarily small integers that can be used as table indices.

dwThreadId

Specifies the identifier of the thread in which the debugging event occurred. A debugger uses this value to locate the debugger's per-thread structure. These values are not necessarily small integers that can be used as table indices.

Specifies additional information relating to the debugging event. This union takes on the type and value appropriate to the type of debugging event, as described in the dwDebugEventCode member.

Remarks

If the WaitForDebugEvent function succeeds, it fills in the members of a DEBUG_EVENT structure.
