- int gd_fragment_index(const DIRFILE *dirfile, const char *entry_name);
This is one of the few GetData functions which does not resolve aliases: supplying the name of an alias as entry_name will return the index of the fragment containing the alias itself and not that of its target.
RETURN VALUEUpon successful completion, gd_fragment_index() returns the requested fragment index. On error, gd_fragment_index() returns -1 and sets the dirfile error a non-zero error value. Possible error values are:
- The library was unable to allocate memory.
- The entry specified by entry_name was not found in the database.
- The supplied dirfile was invalid.
