2.47 - DPMI function 0901h
- Get Virtual Interrupt State
Returns the current state
of the virtual interrupt flag.
In: |
AX = 0902h |
Out: |
CF clear
AL = 0 if virtual interrupts are disabled
AL = 1 if virtual interrupts are enabled |
Notes:
a) This function should
be used in preference to the PUSHF instruction to examine the interrupt
flag, because the PUSHF instruction returns the physical interrupt flag
rather than the virtualized (per-client) interrupt flag. On some DPMI hosts,
the physical interrupt flag will always be enabled, even when hardware
interrupts are not being passed through to the client.
