I'm sure I remember seeing references to this problem in various
places: when I do a LOT of malloc and free using the library routines
from Microsoft, I get my heap mongo fragmented, because they don't
merge adjacent free space. (This is obviously a bug, but never mind
that now....) I vaguely remember that Microsoft has published some
code to do this merging, that one can put into a program and call when
needed. Can anybody give me a pointer to code to merge adjacent free
space in the Microsoft heap, or code for a whole new malloc that will
work in the Microsoft C environment? Anon ftp location would be fine,
or mail it to me maybe if it's small.
Thanks!

There is a book called Advanced C Tips and Techniques that has a whole chapter dedicated to the development of a heap manager. It includes the complete source listing. The complete reference is: Advanced C - Tips and Techniques Paul Anderson and Gail Anderson Stephen G. Kochan and Patrick H. Wood eds. Hayden Books, Indianapolis, Indiana This is also a great book on C in general. Hope this helps.
