I seem to be confused about the use of the heap in Turbo C.  I understand that
coreleft() will not actually return the amount of unused space on the heap.
So how do I find out how much space is actually left?  I seem to remember
seeing somewhere how Turbo C finds the size block that you need, but now I
can't find it.  Can someone tell me:

1) Is the heap separated into paragraphs?  For example, will a malloc(2)
   actually mark off 16 bytes?

2) Can I find out how much space is allocated to a specific pointer? (Actual
   space on the heap)

3) Can I find out how much space is left unused in the entire heap?

If anything else I have said is wrong, I would appreciate any corrections.

Thanks,
