lResult (LONG) - returns

Return codes.

On completion, the handling routine must return a LONG value (lResult):

• Error.
  
• The screen has been successfully redrawn.
  
• The screen has not been completely redrawn; further action is required from the application.

  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
