Oh yes, sort... that reminds me... http://www.gtoal.com/wordgames/sort/sort.[ch] - see the above for the epitome of managing store yourself... It's not pretty and I'm not proud of the actual code but I was very pleased with the way I did the memory management. It allocates a single block of RAM at startup and partitions it rather sneakily for all objects ever needed by the program, I believe as efficiently as is possible. I wrote this because we were sorting text files of 100's of Mb on a machine that had 4Mb of physical ram; gnusort had a serious bug in that you told it how much ram you wanted to use but it then went over your request quite significantly. This was semi-OK on Unix where the use of VM would at least let the program run (albeit thrashing VM a lot) but on our hardware with physical memory only, it *always* failed a malloc at some point. As has been noted in this thread, realloc is evil! The code is well commented. Some might say to excess :-) It's probably one of the most complex pieces of memory management I've had to do in an application, and I didn't want to take the risk that I'd have to do maintenance on it 20 years later, and take one look at it and say "WTF???!" (So I guess that means it'll be due for maintenance in 2008 ;-) ) G
