Ldm-stor-spec-list

Map a list of storage class specifiers to a storage class specifier sequence in the language definition.

Signature

(ldm-stor-spec-list stor-specs) → (mv erp scspecseq)

Arguments

stor-specs — Guard (stor-spec-listp stor-specs).

Returns

scspecseq — Type (c::scspecseqp scspecseq).

The list must be empty, or a singleton with the extern specifier.
