Low-Level DOS Support Services

The Low-Level DOS Support Services are rarely necessary at the application level - they provide interrupt and stack handling services.

Low-Level DOS Support Services
AIL_set_real_vect	installs a real-mode handler real_ptr for interrupt vectnum.
AIL_set_USE16_ISR	creates a 16-bit protected-mode interrupt handler for interrupt vectnum, mapped to an existing bimodal interrupt handler in real-mode memory.
AIL_disable_interrupts	disables hardware interrupts (IRQs).
AIL_restore_interrupts	restores the hardware interrupt state effective prior to the last call to AIL_disable_interrupts (above).
AIL_switch_stack	allows a C or C++ module to change to a different stack whose size and location may be chosen by the programmer.
AIL_restore_stack	returns to the default stack which was in use prior to the last call to AIL_switch_stack.
AIL_get_real_vect	obtains the address of the current real-mode handler for interrupt vectnum.
AIL_call_driver	performs a call to an MSS-compatible sound driver in real-mode memory.
VDI_CALL	specifies the registers passed or returned from a real-mode driver call.
