typedef volatile unsigned long DWORD_ATOM

This type is intended for tagging the locations that will be operated on by the "lwarx/stwcx". instruction pair using the atomic series of inline assembly functions, such as atomicAdd() or atomicSet(). This tag will hopefully remind programmers that unprotected manipulation of the data is not permitted (or intended). Note that integers of this type are required to be on a DWORD boundary. Otherwise an alignment exception is triggered.

Since:
SC2x3 V1.02 - CLIB V1.02
