Given the following code

   char keyChar = (char)getWgt()->GetNfyData();

where GetNfyData() returns a void *, how can I hide the resulting
"cast from pointer to integer of different size" warning?  I'm using
GCC 3.3.

I don't think you can; the warning is there for a reason: because a sizeof(char) is one byte, I think, but sizeof(void *) is 4 bytes, at least on PPC and i386 under the current ABI.


Are you sure it's not returning a pointer to char?, in which case you could just do:

char *keyChar = (char *)getWgt()->GetNfyData();

or:

char keyChar = ((char *)getWgt()->GetNfyData())[0];

Usual disclaimer: typed in mail, may not be correct.
