Function arCheckEntries

modules/dasSQLITE/sqlite/shell.c:22190–22220

** This function assumes that all arguments within the ArCommand.azArg[] ** array refer to archive members, as for the --extract, --list or --remove ** commands. It checks that each of them are "present". If any specified ** file is not present in the archive, an error is printed to stderr and an ** error code returned. Otherwise, if all specified arguments are present ** in the archive, SQLITE_OK

** Linux.
