Been a heavy Blitz3D user and just got started with BlitzMax and trying to grasp things. I wonder if BlitzMax supports the same extension and libraries via declarations or how does that work?

I imagine it differs as .dll is Windows only? What are the options in BlitzMax to add for example lowlevel access to OS in the same way Blitz3D did?

the windows libraries can be imported using the "Import" keyword followed by "-l" + "dll_name" (dll_name is the name of the library you want to import) then use Extern to map the functions

ex:

Import "-luser32"

The "decls" is actually your code
Extern 
	Function GetDC:int (hwnd:int) = "GetDC@4"
End Extern

for external dynamic libraries, you 'll need to load the library
-> LoadLibraryA

it will look like something like this

Local dll:Int = LoadLibraryA ("my_dll.dll")

Global MyDllFunction()

If dll
	MyDllFunction = GetProcAddress (dll, "dll_function_name")
EndIf;
