WinUAE and Windows dll...
Hi all,
I try to use the vector $f0ffc0 to interface winuae to a Windows dll (TM) (R) (c). It works fine with unsigned long values, but how evil to share buffers ?. Address space are completly different!! Any idea  ? please  section text,code ; input A0 dllname ; output D0 dllhandle DLLOpen moveq #100,D0 jsr $00f0ffc0 rts ; input D1 dllhandle DLLClose moveq #103,D0 jsr $00f0ffc0 rts ; input D1 dllhandle ; A0 function or variable name ; output D0 function or variable address DLLGetFuncAddr moveq #101,D0 jsr $00f0ffc0 rts ; input A0 function address ; output D0 return DLLExec moveq #102,D0 jsr $00f0ffc0 rts end |

I've found a tip!
; input void ; output D0 return memory offset DLLGetMemoryOffset moveq #105,D0 jsr $00f0ffc0 rts This routine computes the offset between address 0 and the real memory offset in Windows world. All buffers must be allocated in CHIP, for example toto = AllocMem(512, MEMF_CHIP), then DLLGetMemoryOffset()+toto matches exactly the buffer toto in the DLL. So I can build strange dll for winuae now!
