Vl-scopeexpr-split-right

Split off the rightmost part of a hierarchical scope expression.

Signature

(vl-scopeexpr-split-right x) 
  → 
(mv successp prefix indices lastname)

Arguments

x — Guard (vl-scopeexpr-p x).

Returns

successp — Type (booleanp successp).

prefix — Type (vl-scopeexpr-p prefix).

indices — Type (vl-exprlist-p indices).

lastname — Type (stringp lastname).

This is a thin wrapper around vl-hidexpr-split-right that just sticks the scopes back on.
