Syntax: EXTERN IMPORT Bezeichner [ALIAS "Aliasname"] [AS Typ]
Typ: Schlüsselwort
Kategorie: Bibliotheken

IMPORT wird unter Win32 zusammen mit EXTERN (Module) verwendet, wenn auf globale Variablen aus DLLs zugegriffen werden muss, da in solchen ein Zugriff über eine implizite Pointer-Dereferenzierung geschieht.

' mydll.c: compilieren mit

' gcc -shared -Wl,--strip-all -o mydll.dll mydll.c

__declspec( dllexport ) int MyDll_Data = 0x1234;

' import.bas:

#inclib "mydll"

Extern Import MyDll_Data Alias "MyDll_Data" As Integer



Print "&h" + Hex( MyDll_Data )

Ausgabe:

&h1234

Unterschiede zu QB: neu in FreeBASIC

Unterschiede unter den FB-Dialektformen:
In der Dialektform -lang qb steht IMPORT nicht zur Verfügung und kann nur über __IMPORT aufgerufen werden.
