- * The following are the possible returned values common to all the routines
- * below. The applicability of some of these return values depends on the

- *
- *	CRYPTO_SUCCESS:	The operation completed successfully.
- *	CRYPTO_QUEUED:	A request was submitted successfully. The callback
- *			routine will be called when the operation is done.
- *	CRYPTO_MECHANISM_INVALID or CRYPTO_INVALID_MECH_PARAM
- *			for problems with the 'mech'.
- *	CRYPTO_INVALID_DATA for bogus 'data'
- *	CRYPTO_HOST_MEMORY for failure to allocate memory to handle this work.
- *	CRYPTO_INVALID_CONTEXT: Not a valid context.
- *	CRYPTO_BUSY:	Cannot process the request now. Schedule a
- *			crypto_bufcall(), or try later.
- *	CRYPTO_NOT_SUPPORTED and CRYPTO_MECH_NOT_SUPPORTED:
- *			No provider is capable of a function or a mechanism.

- *	mech:	crypto_mechanism_t pointer.
- *		mech_type is a valid value previously returned by

- *		When the mech's parameter is not NULL, its definition depends

- * Description:
- *	Asynchronously submits a request for, or synchronously performs the
