Function esp_idf_sys::psa_mac_abort

pub unsafe extern "C" fn psa_mac_abort(
    operation: *mut psa_mac_operation_t,
) -> psa_status_t

Abort a MAC operation.

Aborting an operation frees all associated resources except for the \p operation structure itself. Once aborted, the operation object can be reused for another operation by calling psa_mac_sign_setup() or psa_mac_verify_setup() again.

You may call this function any time after the operation object has been initialized by one of the methods described in #psa_mac_operation_t.

In particular, calling psa_mac_abort() after the operation has been terminated by a call to psa_mac_abort(), psa_mac_sign_finish() or psa_mac_verify_finish() is safe and has no effect.

\param[in,out] operation Initialized MAC operation.

It is implementation-dependent whether a failure to initialize results in this error code.
