Hi all
I try to use the syscall package to call a native Windows API and
struggling with the call parameters. I calling the api
HRESULT WINAPI AmsiInitialize(
_In_ LPCWSTR appName,
_In_ DWORD coInit,
_Out_ HAMSICONTEXT *amsiContext
);
my test app looks like this
package main
import (
"fmt"
"syscall"
"unsafe"
"golang.org/x/sys/windows"
)
func main() {
h := windows.MustLoadDLL("Amsi.dll")
defer h.Release()
ainit := h.MustFindProc("AmsiInitialize")
auinit := h.MustFindProc("AmsiUninitialize")
ascanstring := h.MustFindProc("AmsiScanString")
var context uintptr
r1, r2, err := ainit.Call(uintptr(unsafe.Pointer(syscall.
StringToUTF16Ptr("Scanner Tool"))), 0, uintptr(unsafe.Pointer(&context)))
fmt.Println(context)
fmt.Println(r1, r2, err)
// output:
// 0
// 2147942487 0 The operation completed successfully.
unfortunately the call succeeds but the context is still zero. Probably i
call the function with the wrong parameters but i can't work it out.
Has anybody a idea what could be wrong?
Thank you in advance
