[ECOS] cyg_mempool_info

[Srinivasan Sriram]

Hello!

I create a variable memory pool of size 4096.
A thread claims a block size of 4000.

typedef struct {
   cyg_int32 totalmem;
   cyg_int32 freemem;
   void *base;
   cyg_int32 size;
   cyg_int32 blocksize;
   cyg_int32 maxfree; // The largest free block
  } cyg_mempool_info;

Using this structure I get -

totalmem 4080
freemem 64
base 71776
size 4096
blocksize -1
maxfree 64 

---

Though maxfree is 64, I'm unable to even obtain a
block of 60 from the pool.
How did the figure of 64 end up as freemem? (It should
be more).
And how do I compute how much memory is now available
in the pool so that my mempool_var_alloc will not
fail?

Thanks
Kavita
