ASPCloseAll
XPPParmBlkPtr xParamBlock; pointer to an AppleTalk parameter block Boolean async; 0=await completion; 1=immediate return ASPCloseAll closes every session that the driver has active, aborting all active requests and invoking the attention routines where provided.
xParamBlock is a pointer to a parameter block structure. The relevant fields are
as follows:
async is a Boolean value. Use FALSE for normal ( synchronous) operation or TRUE to enqueue the request and resume control immediately. See Async I/O.
Notes: This call should be used carefully. ASPCloseAll can be used as a system level resource for making sure all sessions are closed prior to closing the
driver.
