_LDDSTD - load then store descriptor.
Usage:
_lddstd(out, in);
Where:
- void *out;
- points to a location where "_lddstd" can store the descriptor.
This location must be at least two machine words long
and aligned on a double-word boundary.
- void *in
- points to a descriptor or shrink vector.
For example, it could point to a "struct _vector" as
produced by the "_vector" function.
Description:
"_lddstd" is a low-level routine that lets you manipulate
descriptors and/or shrink vectors.
It executes an LDD machine instruction to load the descriptor
from "*in", then an STD machine instruction to store the
descriptor in "*out".
For further information, see the appropriate hardware
manuals for explanations of the LDD and STD instructions.
