9 Fixed Memory Allocator
------------------------------------------------------------------------------------------
Clipper 5.0 subsystems use virtual memory to contain code or data that
needs to be dynamically managed. Some allocations are not appropriate
for VM (e.g., system tables which must remain in the same location
throughout execution). A C-style fixed memory allocator is included
for this purpose.
The fixed memory system allocates one or more VM segments and
permanently locks them in real memory. Space within these segments is
then parceled out as needed. Since fixed segments are never unlocked,
the VMM locates them at the low end of the swap space to prevent them
from interfering with other operations.
