VB 调用vc 的dll问题,dll参数是双重指针

[cryptonym]

vc的dll函数是这么声明的：
bool SAAT_TCPInit (void** pHandle,char *pHostName,int nsocketPort)

我现在要用vb调用vc的dll，该怎么声明这个函数以及怎么调用 呢？

[Tiger_Zhao]

Private Declare Function SAAT_TCPInit Lib "abc.dll" _
    (ByRef pHandle As Long, ByVal pHostName As String, ByVal nsocketPort As Long _
    ) As Byte

Private Sub Command1_Click()
    Dim hHandle As Long
    Dim pHandle As Long
    
    pHandle = VarPtr(hHandle) '指针
    Call SAAT_TCPInit pHandle, ... 'ByRef 参数自动取指针的指针
End Sub

双重指针就是引用传递指针。
