ROSCO,
Well, I was wrong about the inline function. I sure am learning a lot these
days 8-)
I tried it both ways (inline func and macro)... turns out the macro produces
less code by about 50 bytes. (that will be the last time I post without
trying it out first! sorry about that!)
Also, last night I discovered that in mm_try_join (mm.c) The while loop is
only terminated when a non-free memory block is found. I am wondering what
will happen if you mm_try_join on a block and all the remaining blocks are
free... the next pointer would overflow (wrap-around?). Is there something
that I don't know... like a in-use block at the end that would prevent this?

| I know it is fairly trivial, but it is a start. I am working on some other things... hopefully to be included either in patch form or in 0.2.6 (if/when it comes about). I like the idea of the inline function best, but will leave that up for debate. (...) (23 years ago, 21-Mar-02, to lugnet.robotics.rcx.legos)
