custom memory manager..

Hello,

I am developing a user level memory manager for a protocol stack. It
will replace the usual malloc() by something like my_malloc() and free
by my_free(). The basic idea is to minimize the chances of memory non-
avaliabiltiy, minimize system calls at run time thereby minimizing
risk for failure, and use the memeory in an effcient way.

The problem is i donot want to change the prototype of my_malloc which
is currently same as malloc() but I also want to associate debug
information along wth every buffer allocated.

For example, if function f1() from task T1 calls my_malloc(), then I
want to associate things like

1. task_id,
2. regiser counetrs,
3. stack trace or any other relevant debug info that would help me
debug any memory crash.

Can any one suggest how can I do it? I mean which system call will hel
me and whatother info (other then the one i have mentioned) can be
used?
