DEBUG_EVENT structure (minwinbase.h)
Describes a debugging event.
Syntax
typedef struct _DEBUG_EVENT {
DWORD dwDebugEventCode;
DWORD dwProcessId;
DWORD dwThreadId;
union {
EXCEPTION_DEBUG_INFO Exception;
CREATE_THREAD_DEBUG_INFO CreateThread;
CREATE_PROCESS_DEBUG_INFO CreateProcessInfo;

Members
dwDebugEventCode
Type: DWORD
The code that identifies the type of debugging event. This member can be one of the following values.
| Value | Meaning |
|---|---|
|
Reports a create-process debugging event (includes both a process and its main thread). The value of u.CreateProcessInfo specifies a CREATE_PROCESS_DEBUG_INFO structure. |
|
Reports a create-thread debugging event (does not include the main thread of a process, see `CREATE_PROCESS_DEBUG_EVENT`). The value of u.CreateThread specifies a CREATE_THREAD_DEBUG_INFO structure. |
|
Reports an exception debugging event. The value of u.Exception specifies an EXCEPTION_DEBUG_INFO structure. |
|
Reports an exit-process debugging event. The value of u.ExitProcess specifies an EXIT_PROCESS_DEBUG_INFO structure. |
|
Reports an exit-thread debugging event. The value of u.ExitThread specifies an EXIT_THREAD_DEBUG_INFO structure. |
|
Reports a load-dynamic-link-library (DLL) debugging event. The value of u.LoadDll specifies a LOAD_DLL_DEBUG_INFO structure. |
|
Reports an output-debugging-string debugging event. The value of u.DebugString specifies an OUTPUT_DEBUG_STRING_INFO structure. |
|
Reports a RIP-debugging event (system debugging error). The value of u.RipInfo specifies a RIP_INFO structure. |
|
Reports an unload-DLL debugging event. The value of u.UnloadDll specifies an UNLOAD_DLL_DEBUG_INFO structure. |
dwProcessId
Type: DWORD
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
Type: DWORD
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.
u
Any 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.
u.Exception
Type: EXCEPTION_DEBUG_INFO If the dwDebugEventCode is EXCEPTION_DEBUG_EVENT (1), u.Exception specifies an EXCEPTION_DEBUG_INFO structure.
u.CreateThread
Type: CREATE_THREAD_DEBUG_INFO If the dwDebugEventCode is CREATE_THREAD_DEBUG_EVENT (2), u.CreateThread specifies an CREATE_THREAD_DEBUG_INFO structure.
u.CreateProcessInfo
Type: CREATE_PROCESS_DEBUG_INFO If the dwDebugEventCode is CREATE_PROCESS_DEBUG_EVENT (3), u.CreateProcessInfo specifies an CREATE_PROCESS_DEBUG_INFO structure.
u.ExitThread
Type: EXIT_THREAD_DEBUG_INFO If the dwDebugEventCode is EXIT_THREAD_DEBUG_EVENT (4), u.ExitThread specifies an EXIT_THREAD_DEBUG_INFO structure.
u.ExitProcess
Type: EXIT_PROCESS_DEBUG_INFO If the dwDebugEventCode is EXIT_PROCESS_DEBUG_EVENT (5), u.ExitProcess specifies an EXIT_PROCESS_DEBUG_INFO structure.
u.LoadDll
Type: LOAD_DLL_DEBUG_INFO If the dwDebugEventCode is LOAD_DLL_DEBUG_EVENT (6), u.LoadDll specifies an LOAD_DLL_DEBUG_INFO structure.
u.UnloadDll
Type: UNLOAD_DLL_DEBUG_INFO If the dwDebugEventCode is UNLOAD_DLL_DEBUG_EVENT (7), u.UnloadDll specifies an UNLOAD_DLL_DEBUG_INFO structure.
u.DebugString
Type: OUTPUT_DEBUG_STRING_INFO If the dwDebugEventCode is OUTPUT_DEBUG_STRING_EVENT (8), u.DebugString specifies an OUTPUT_DEBUG_STRING_INFO structure.
u.RipInfo
Type: RIP_INFO If the dwDebugEventCode is RIP_EVENT (9), u.RipInfo specifies an RIP_INFO structure.
Remarks
If the WaitForDebugEvent function succeeds, it fills in the members of a DEBUG_EVENT structure.
