are the function pointer types used within a STORE loader.
The functions pointed at define the functionality of the given loader.
This function is expected to return 1 on success, 0 on error.
+=item B<OSSL_STORE_find_fn>
+
+This function takes a B<OSSL_STORE_LOADER_CTX> pointer and a
+B<OSSL_STORE_SEARCH> search criterion, and is used to tell the loader what
+to search for.
+
+When called with the loader context being B<NULL>, this function is expected
+to return 1 if the loader supports the criterion, otherwise 0.
+
+When called with the loader context being something other than B<NULL>, this
+function is expected to return 1 on success, 0 on error.

This function takes a B<OSSL_STORE_LOADER_CTX> pointer and a B<UI_METHOD>
=item B<OSSL_STORE_error_fn>
This function takes a B<OSSL_STORE_LOADER_CTX> pointer and is expected to
-return 1 to indicate that an error occured in a previous call to the
+return 1 to indicate that an error occurred in a previous call to the
B<OSSL_STORE_load_fn> function.
It is otherwise expected to return 0.
