Hook Read calls

[ShakedGold]

I tried hooking a Read call which does work:

//export detourReadFile
func DetourReadFile(hFile C.HANDLE, lpBuffer C.LPVOID, nNumberOfBytesToRead C.DWORD, lpNumberOfBytesRead C.LPDWORD, lpOverlapped C.LPOVERLAPPED) C.BOOL {
	result, _, lastErr := syscall.SyscallN(
		uintptr(unsafe.Pointer(readTrampoline)),
		uintptr(unsafe.Pointer(hFile)),
		uintptr(unsafe.Pointer(lpBuffer)),
		uintptr(C.DWORD(uint(nNumberOfBytesToRead))),
		uintptr(unsafe.Pointer(lpNumberOfBytesRead)),
		uintptr(unsafe.Pointer(lpOverlapped)),
	)
	if result == 0 {
		fmt.Println("Error reading file: ", lastErr)
		return C.BOOL(0)
	}
        return C.BOOL(result)
}

The hooking most of the time works but sometimes I get an error:
Error reading file: The pipe has been ended

Also the program freezes and refuses to continue (If I remove the read hooking, It is not freezing anymore), Am I doing something wrong here?

I don't know if this the error related to the freezing.
