The facilities are the same as for local_scan. See the chapter on that, and use one of the functions documented in local_scan.h For your purpose, that probably means one of string_sprintf() string_copy() string_copyn() Those three return a string in freshly-allocated memory. Freeing is handled for you; it's assumed you're not going overboard within a single processing phase (I'd not recommend attempting to prove that ACLs are Turing-complete, nor write a Game-of-Life program in string expansions).
