Return:
CF clear if successful BX = event code (see #00479) CX = event information (APM v1.2) if BX=0003h or BX=0004hbit 0:
PCMCIA socket was powered down in suspend state. CF set on error AH = error code (03h,0Bh,80h) (see #00473)
Notes: Although power management events are often asynchronous, notification will not be made until polled via this call to permit software to only receive event notification when it is prepared to process power management events; since these events are not very time- critical, it should be sufficient to poll once or twice per second. The critical resume notification is made after the system resumes from an emergency suspension; normally, the system BIOS only notifies its partner that it wishes to suspend and relies on the partner to actually request the suspension, but no notification is made on an emergency suspension. Should not be called from within a hardware interrupt handler to avoid reentrance problems
