VS Error from macro AudioMemory(num) in AudioStream.h

[CraigF]

Visual Studio / Visual Micro give an error when attempting to use the macro

AudioMemory(60);

The error message is "Expression expected" and the cause of the error is the parentheses wrapped around the macro definition found in file AudioStream.h as follows:

#define AudioMemory(num) ({ \
	static DMAMEM audio_block_t data[num]; \
	AudioStream::initialize_memory(data, num); \
})

Removing the outer parentheses resolves the error message.

My question: is it OK to just remove the parentheses in the library header file, or would that break something somewhere else?

Would I be better off to just put the inner code in my program explicitly?

thanks!

Probably fine to delete the parens.

That should work too, but don't name anything else "data" within its scope.

thanks much!
