DOS/32 Advanced DOS Extender - Programmer's Reference 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.
