Heap free size measuring functions

[Nick.SIMON at syntegra.bt.co.uk]

Chaps,

I need to be able to monitor the heap for diagnostics.  I have writen a
function _Heap_Scan for the kernel end of things, and had planned to put a
library function in malloc.c.

2 questions:

 - Is it OK to put stuff in libc
 - Is there a standard function template "out there" that this could conform
to?


Regards,
