ossl_method_store_init() initialises the method store subsystem in the scope of

ossl_method_store_cleanup() cleans up and shuts down the implementation method
-store subsystem in the scope of the library context B<ctx>.
+store subsystem in the scope of the library context I<ctx>.
ossl_method_store_new() create a new empty method store using the supplied
-B<ctx> to allow access to the required underlying property data.
+I<ctx> to allow access to the required underlying property data.
-ossl_method_store_free() frees resources allocated to B<store>.
+ossl_method_store_free() frees resources allocated to I<store>.
-ossl_method_store_add() adds the B<method> constructed from an implementation in
-the provider B<prov> to the B<store> as an instance of an algorithm indicated by
-B<nid> and the property definition B<properties>, unless the B<store> already
-has a method from the same provider with the same
B<nid> and B<properties>.

+If the I<method_up_ref> function is given, it's called to increment the

+ossl_method_store_remove() removes the I<method> identified by I<nid> from the

+ossl_method_store_fetch() queries I<store> for a method identified by I<nid>
+that matches the property query
I<prop_query>.

-ossl_method_store_set_global_properties() sets method B<store> wide query

=head2 Cache Functions
-ossl_method_store_cache_get() queries the cache associated with the B<store>
-for a method identified by B<nid> that matches the property query
-The result, if any, is returned in B<method>.
+ossl_method_store_cache_get() queries the cache associated with the I<store>

+The result, if any, is returned in I<method>.
-ossl_method_store_cache_set() sets a cache entry identified by B<nid> with the
-property query B<prop_query> in the B<store>.
-Future calls to ossl_method_store_cache_get() will return the specified B<method>.

+The I<method_up_ref> function is called to increment the
