Where size is the number of bytes of memory required.
&blockp is a pointer to storage for the returned pointer to the memory
block.
&memsize is a pointer to storage for the actual usable size in bytes of the
memory block at blockp. memsize may be slightly larger than size.
It is valid to replace &memsize with &size to update your size
variable.
handle is a memory handle assigned by the Memory Manager in a
previous call to ajmhan. Note that the handle is a pointer.
Results Interrupts are disabled and then restored to their state at the time of the
call.
Status is returned.
AEROK = Call successful
blockp is a pointer to a block of memory.
memsize is the actual size of that block.
AERMNA = Memory not available
blockp is undefined.
memsize is the size of the largest block of memory which is
currently available using the given handle.
AERMIB = handle is an invalid memory handle.
blockp and memsize are undefined.
If memory is allocated, the use count for the memory block is set to one.
