=head1 SYNOPSIS
void ossl_provider_teardown(const OSSL_PROVIDER *prov);
const OSSL_PARAM *ossl_provider_gettable_params(const OSSL_PROVIDER *prov);
int ossl_provider_get_params(const OSSL_PROVIDER *prov, OSSL_PARAM params[]);
+ int ossl_provider_get_capabilities(const OSSL_PROVIDER *prov,
+ const char *capability,
+ OSSL_CALLBACK *cb,
+ void *arg);
const OSSL_ALGORITHM *ossl_provider_query_operation(const OSSL_PROVIDER *prov,
int operation_id,
int *no_cache);
It should treat the given I<OSSL_PARAM> array as described in
L<OSSL_PARAM(3)>.
+ossl_provider_get_capabilities() calls the provider's I<get_capabilities> function,
+if the provider has one. It provides the name of the I<capability> and a
+callback I<cb> parameter to call for each capability that has a matching name in
+the provider. The callback gets passed OSSL_PARAM details about the capability as
+well as the caller supplied argument I<arg>.
+
ossl_provider_query_operation() calls the provider's
I<query_operation> function, if the provider has one.
It should return an array of I<OSSL_ALGORITHM> for the given
ossl_provider_set_operation_bit() and ossl_provider_test_operation_bit()
return 1 on success, or 0 on error.
+ossl_provider_get_capabilities() returns 1 on success, or 0 on error.
+If this function isn't available in the provider or the provider does not
+support the requested capability then 0 is returned.
