RESPEC
RESPEC changes the attributes of the expression x to
the type t without changing the bit value of the
expression.
- t
- Name of a scalar type
- p
- A scalar expression
x must have the same size as t,
and if either x or t is UNALIGNED
BIT, both must be UNALIGNED BIT (in which case the function is somewhat
uninteresting because it would do nothing).
As an example, if t is a type with the attributes
LIMITED ENTRY, RESPEC( t, sysnull() ) would return a "null" function
pointer.
