#3160 assigned Feature Request

Allow Null to specify NULL pointer for more DllCall() pointer types.

Reported by: Valik Owned by: Jon
Milestone: Component: AutoIt
Version: Severity: None
Keywords: Cc:


I see that using the Null keyword with str and wstr parameters of DllCall() causes AutoIt to pass a NULL pointer. That's very useful. I'd like to see it extended to all pointer types. If I pass Null to a "DWORD*" it seems to treat it like I'm passing a pointer to a DWORD with value 0 as opposed to treating it as a NULL pointer. This behavior results in needing to write messy code like this:

Func FakeFunction($iParameter)
    Local $sParamType = "DWORD*"
    If $iParameter = Null Then $sParamType = "ptr"
    DllCall("fake.dll", "none", "FakeFunction", $sParamType, $iParameter)


By allowing Null to specify a NULL pointer for all pointer types that code becomes:

Func FakeFunction($iParameter)
    DllCall("fake.dll", "none", "FakeFunction", "DWORD*", $iParameter)


Much cleaner and easier to read and write.
