[D3D framework for D3D8 and D3D9]

hans211 im doing my best to find out how to unhook something but i just dont get it

 

im using theese funktion:

void  DetourRemove(BYTE *src, BYTE *restore, const int len=0);

BOOL DetourRemove(LPVOID lpDetourCreatePtr);



BOOL DetourRemove(LPVOID lpDetourCreatePtr)
{
PBYTE pbMallocPtr = NULL;
DWORD dwFuncOrig = NULL;
DWORD dwProt = NULL;
int i=0;

if((pbMallocPtr = (PBYTE)lpDetourCreatePtr) == NULL)
	return FALSE;

// Find the orig jmp32 opcode sig
for(i=0; i<=DETOUR_MAX_SRCH_OPLEN; i++)
{
	if(pbMallocPtr[i] == SIG_OP_0 
		&& pbMallocPtr[i+1] == SIG_OP_1
		&& pbMallocPtr[i+2] == SIG_OP_2)
		break;

	if(i == DETOUR_MAX_SRCH_OPLEN)
		return FALSE;
}

// Calculate the original address
pbMallocPtr += (i-JMP32_SZ+1); // Inc to jmp
dwFuncOrig = *(DWORD*)pbMallocPtr; // Get 32bit jmp
pbMallocPtr += BIT32_SZ; // Inc to end of jmp
dwFuncOrig += (DWORD)pbMallocPtr; // Add this addr to 32bit jmp
dwFuncOrig -= (i-JMP32_SZ); // Dec by detour len to get to start of orig

// Write the overwritten bytes back to the original
VirtualProtect((LPVOID)dwFuncOrig, (i-JMP32_SZ), PAGE_READWRITE, &dwProt);
memcpy((LPVOID)dwFuncOrig, lpDetourCreatePtr, (i-JMP32_SZ));
VirtualProtect((LPVOID)dwFuncOrig, (i-JMP32_SZ), dwProt, new DWORD);

return TRUE;
}

 

 

can you pleas tell me how to unhook Drawindexedprimitive as example
