XXX_PowerUp and XXX_PowerDown
XXX_PowerUp and XXX_PowerDown
You can use the XXX_PowerUp and XXX_PowerDown stream interface functions to implement suspend and resume functionality. The kernel calls XXX_PowerDown right before powering down the CPU and XXX_PowerUp right after powering it up. It is important to note that the system operates in single-threaded mode during these stages with most system calls disabled. For this reason, Microsoft recommends using the XXX_IOControl function instead of XXX_PowerUp and XXX_PowerDown to implement power management features, including suspend and resume functionality.
CAUTION
Power management restrictions
If you implement suspend and resume functionality based on the XXX_PowerUp and XXX_PowerDown functions, avoid calling system APIs, particularly thread-blocking APIs, such as WaitForSingleObject. Blocking the active thread in single-threaded mode causes an unrecoverable system lockup.
