Vl-compoundstmt->exprs

Get all immediate sub-expressions from any compound statement.

Signature

(vl-compoundstmt->exprs x) → exprs

Arguments

x — Guard (vl-stmt-p x).

Returns

exprs — Type (vl-exprlist-p exprs).

Note that this only returns the top-level expressions that are directly part of the statement.
