Short: Resourse tracking mem allocator MEM: A memory management safety net. written by --------------- Simon Bullen 10 Hogan Street Sunbury 3429 Australia --------------- In this archive, there should be the following files: mem.doc 3594 bytes mem.c 6801 bytes mem.h 523 bytes Ever had the problem of a program you're trying to debug swallowing 24 bytes somewhere, and not knowing where? Or perhaps you're playing around with one of the more complex memory structures, and it gurus a lot due to incorrect memory frees? Painful to debug, aren't they? Well, no longer!! With these two teeny files, your programs will crash from memory mismanagement never again! mem.c provides a safety net around all your calls to AllocMem and FreeMem, recording what you've allocated, and where you allocated (ie where in the source-code). Then, when you do something wrong (like try to free something you never allocated), it simply displays a nice little debug message like this: hello.c 44: Incorrect free size. (64 instead of 2300) or this: hello.c 45: Free twice (?). ($34, 2478756) There must be very few Amiga programmers out there who haven't had the "Free Twice" guru! mem.c also provides a mechanism to find out just what you haven't gotten around to freeing yet (you've been -meaning- to for ages...): hello.c 76: Memory List Address Size File Line ------- ---- ---- ---- $123450 24 hello.c 42 $200000 4500 there.c 97 Useful, eh? But that's not all!! Gone are the days when you have to reboot your computer every time your rogue program eats up all your precious memory; A simple call will free everything you allocated! Ok, enough of the advertisement; here's how to do it: Simply #include "mem.h" (make sure you put that AFTER #include "proto/exec.h" !!!!!!). Link with mem.o, and place calls to ShowMemList() and ClearMemList() where-ever you feel appropriate. (At the end of main() is the most obvious place, though the more industrious could put the calls in break & exit traps.) To find out how it works, read the extensive documentation in mem.c.

If you find it useful (like it saves you 3 days of debugging time), send whatever you feel appropriate ($10 would be most welcome!). I would be very interested to here any comments, suggestions, and flames you may have.
