<p><b>Notes:</b>
|
|
Called by DPMS.EXE and EMM386.EXE.
|
|
The handler for this function may be set by one of the subfunctions
|
|
of AX=2780h/CL=01h; the default handler returns AX=BX=FFFFh and
|
|
CX=0001h <a href="rb-4716.htm#Table2739" tppabs="http://www.ctyme.com/intr/rb-4716.htm#Table2739">(see #02739)</a>.
|
|
This API is only available if AX=12FFh/BX=0EDCh returns successfully;
|
|
because the request is handled on the initial trap to the memory
|
|
manager caused by INT instructions, this API must be invoked with
|
|
an actual INT 2F instruction instead of some simulation such as a
|
|
far call to the address in the interrupt vector table
