Обсуждение: (void *) with shmat

Hello together,


In ipc.c, function InternalIpcMemoryCreate there is the following line of code:
memAddress = shmat(shmid, 0, 0);

this line should be changed to:
memAddress = (void *) shmat(shmid, 0, 0);


at function IpcMemoryCreate there is the following line of code:
memAddress = shmat(shmid, 0, 0);

this line should be changed to:
memAddress = (void *) shmat(shmid, 0, 0);


This will avoid problems with MetroWerks CodeWarrior compiler.

Thanks

Ulrich Neumann

Why is this needed?

shmat is defined as returning a void *. Is it not so with MetroWerks?

What, pray tell, does MetroWerks think shmat returns?
