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.

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.
