Name=HeapAllocESTACK
Type=Function
Subtype=ROM Call
Header Files=alloc.h
Definition=HANDLE HeapAllocESTACK (unsigned long Size);

[ROM Call]
Index=$91

[Description]
Like <A HREF="$$LINK(alloc.h/HeapAlloc)">HeapAlloc</A>, but reduces the size of the expression stack if necessary.

[Explanation]
HeapAllocESTACK works like <A HREF="$$LINK(alloc.h/HeapAlloc)">HeapAlloc</A>, but 
reduces the size of the expression stack if necessary (i.e. if there is not
enough memory). Returns <A HREF="$$LINK(alloc.h/H_NULL)">H_NULL</A> if there is not enough
memory even after reducing the size of the expression stack.
