Hi all,
I'm wondering if there are differences between NewPtr and malloc,
DisposePtr and free. Which ones are better? or just same?
They are both the same, i would use malloc vs NewPtr, since its more
standard (exact same code will work everywhere)
Hello,
Althrough they might seem the same, they are not. ptr = NewPtr(size)
is mac os toolbox function which allocates free pointer block. You
may want to allocate ptr = NewPtrClear(size) --- a cleared pointer
block. You can get size of that block GetPtrSize(ptr) or tell user
why the allocation failed err = MemError() right after a call to
NewPtr. You may also resize the block using SetPtrSize and MemError
afterwards.
