semantic-c-reconstitute-token is a byte-compiled function defined in c.el.gz.

Signature

(semantic-c-reconstitute-token TOKENPART DECLMODS TYPEDECL)

Documentation

Reconstitute a token TOKENPART with DECLMODS and TYPEDECL.

This is so we don't have to match the same starting text several times. Optional argument STAR and REF indicate the number of * and & in the typedef.
