_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.
