Peek & poke from/to a MemoryBlock

[Pierre_Vareilles]

Can anyone tell me why I can’t get function pointer to get/set values of a MemoryBlock. Thanks

REALobject mb = NULL;

mb = REALnewInstanceWithClass(memoryblockRef);
if (!mb)
   return NULL;

typedef void (*setByte)(REALobject obj, RBInteger offset, unsigned char val);
setByte mbSetByte = (setByte)REALLoadObjectMethod(mb, "Byte(offset As Integer, Assigns val As UInt8)");
    
typedef RBInteger (*getByte)(REALobject obj, RBInteger offset);
getByte mbGetByte = (getByte)REALLoadObjectMethod(mb, "Byte(offset As Integer)");

if ((!mbGetByte) || (!mbSetByte))
    return mb; // return NULL ??????
    
REALSetPropValueInteger(mb, "Size", bufSize);

Please read older thread first

REALMemoryBlockGetPtr replacement

If you mean poking inside the REALobject itself, don’t. The internals are subject to change and it will only hurt users. I would recommend against this too, though more of an academic point to warn about doing this in other situations. It’s possible, albeit very unlikely, that you could get given a subclass of MemoryBlock that overrides this method.

Thanks Christian. Invaluable help as usual.
