DetourIsHelperProcess
Check if the current process is a helper process or a target process.
Definition
BOOL DetourIsHelperProcess(VOID);
Return value
Returns TRUE if this process is a helper process.
Returns FALSE if this process is a target process.
Remarks
When creating a 32-bit target process from a 64-bit parent process or
creating a 64-bit target process from a 32-bit parent process, the
DetourCreateProcessWithDllEx API
must create a temporary helper process. It loads a copy of the
user-supplied DLL into the helper process using the rundll32.exe
mechanism. The user-supplied DLL should call DetourIsHelperProcess
within its DllMain function to determine if it has been loaded into a
helper process or into a target process.
When a user-supplied DLL is loaded into a helper process, it must
not detour any functions. Instead, it should perform no operations in
DllMain. The user-supplied DLL must also export the
DetourFinishHelperProcess API as
its Ordinal 1 export function.
For more information, see Detouring 32-bit and 64-bit Processes.
