=head1 DESCRIPTION
I<OSSL_PROVIDER> is a type that holds all the necessary information
ossl_provider_dso() returns a reference to the module, for providers
that come in the form of loadable modules.
-ossl_provider_module_name() returns the file name of the module, for
+ossl_provider_module_name() returns the filename of the module, for
providers that come in the form of loadable modules.
ossl_provider_module_path() returns the full path of the module file,
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
I<operation_id>.
+ossl_provider_set_operation_bit() registers a 1 for operation I<bitnum>
+in a bitstring that's internal to I<provider>.
+
+ossl_provider_tests_operation_bit() checks if the bit operation I<bitnum>
+is set (1) or not (0) in the internal I<provider> bitstring, and sets
+I<*result> to 1 or 0 accorddingly.
+
=head1 NOTES
Locating a provider module happens as follows:
This may be NULL, and is perfectly valid, as it denotes the default
global library context.
-ossl_provider_teardown() doesnt't return any value.
+ossl_provider_teardown() doesn't return any value.
ossl_provider_gettable_params() returns a pointer to a constant
I<OSSL_PARAM> array if this function is available in the provider,
ossl_provider_get_params() returns 1 on success, or 0 on error.
If this function isn't available in the provider, 0 is returned.
+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.
