/**
* \brief Get the number of ops that a key agreement
* operation has taken so far. If the operation has
* completed, then this will represent the number of
* ops required for the entire operation.
* After initialization or calling \c
* psa_key_agreement_iop_abort() on the operation,
* a value of 0 will be returned.
*
* \warning This is a beta API, and thus subject to change
* at any point. It is not bound by the usual
* interface stability promises.
*
* This is a helper provided to help you tune the
* value passed to \c
* psa_interruptible_set_max_ops().
*
* \param operation The \c psa_key_agreement_iop_t to use. This must
* be initialized first.
*
* \return Number of ops that the operation has taken so
* far.
