HH
O/S
is
not
reentrant.
For
this
reason, device
drivers
and
interrupt
service routines
can't
call
HH
0/S
functions.
If
a
device
driver,
or
an
interrupt
service routine
needs
to
be
able
to find
the
absolute
address
of
a
file
it
may
do so
using
this interrupt.
If
HH
O/S
is
not able
to
supply
the
file
address
at
the time
of
the
call,
the
Invalid
Access
Request
error
will
be
returned.
In
this
case, the
program
should repeatedly
call
INT 46h
until
this
error
no
longer occurs.
If
BX
contains
OFFFFh,
the
address
of
the
AMI
for
the
currently
executing
program
is
returned.
