If you need a function to tell you how much memory is available to 
`malloc', then there is no such function in DJGPP.  You can only check 
how much memory is available to your program (this includes both physical 
and virtual, both free and already allocated), and how much physical 
memory is still free (outside your program's address space).  The memory 
that is owned by `malloc' but is on the list of free blocks that `malloc' 
maintains cannot be reported, unless somebody writes a function that 
walks the internal data structures used by `malloc' and counts the free 
blocks.
