AllocMem() and FreeMem()
    These are system-wide memory allocation and deallocation routines.
    They use a memory free-list owned and managed by the system.

AvailMem()
    This routine returns the number of free bytes in a specified type of
    memory.

TypeOfMem()
    This routine returns the memory attributes of a specified memory
    address.

CopyMem()/CopyMemQuick()
    CopyMem() is a general purpose memory copy routine. CopyMemQuick() is
    an optimized version of CopyMemQuick(), but has restrictions on the
    size and alignment of the arguments.
