I am fairly new to the C/Mac environment, but from what I read so far about the Mac, memory seems to be allocated with double pointers (handle) so that the System can recompact it without breaking your code. Now, if you use the malloc defined in the ANSI C library of THINK C 4.0, what is the malloc really doing: - is it getting a chunk of memory which is LOCK every time you call malloc, and as a result you might end up with a swiss cheese memory after a bunch of malloc and free, - the application reserves a very big chunk of memory at the beginning, it is LOCKED, but as you malloc and free inside this big block, Think C is able to recompact the memory in the block itself.(if it is this solution, is there any way to specify the size of this block, grow it?) - is it getting a standard handle, and making some kind of translations for every memory references, (this cannot be the solution, can it?) - none of the above, My concern is really to figure out if writing a big application using the toolbox and using the ANSI C library and malloc is doomed to failure because of memory management problems.
