Hi Guys,
I have defined a type of variable using typedef called MultiBuffer, then I created an array of MultiBuffers.
I have a function that returns a pointer to one of the positions of the array, i.e. a MultiBuffer, when there are no more Multibuffer available for use I would like to return a NULL pointer to signal that there are no more pointers available.
When I used this on Pelles C it worked fine but in LPCXpresso it says it is not defined. I get that, but is there a way of doing the same thing.
I know I can get around this by returning a flag instead that can be just an int but that will make the function a bit messier.
Thanks
Best Regards
