- pascal OSErr IndexedSearch(CSParamPtr pb,

- /* ¶ Search in and below a directory.
- The IndexedSearch function performs an indexed search in and below the
- specified directory using the same parameters (in pb) as is passed to
- PBCatSearch. See Inside Macintosh: Files for a description of the
- parameter block.
-
- pb input: A CSParamPtr record specifying the volume to search
- and the search criteria.
- output: Fields in the parameter block are returned indicating
- the number of matches found, the matches, and if the
- search ended with noErr, the CatPosition record that
- lets you resume a search where the last search left
- off.
- dirID input: The directory to search. If fsRtDirID is passed,
- the entire volume is searched.
-
- Note: If you use a high-level debugger and use ioSearchTime to limit
- the length of time to run the search, you'll want to step over
- calls to IndexedSearch because it installs a Time Manager task.
- Most high-level debuggers don't deal gracefully with interrupt
- driven code.

- The PBCatSearchSyncCompat function uses PBCatSearch (if available) or

- using a set of search criteria that you specify. It builds a list of all
- files or directories that meet your specifications.
