On completion, the handling routine must return a handle to the saved bits (hsbBits) or 0 to indicate that the bits were not saved or that an error occurred.

Possible Errors Detected: When an error is detected, the handling routine must call WinSetErrorInfo to post the condition. Error codes for conditions that the handling routine is expected to check include:

PMERR_DEV_FUNC_NOT_INSTALLED PMERR_INV_HDC
