Function esp_idf_svc::hal::sys::psa_cipher_abort

pub unsafe extern "C" fn psa_cipher_abort(
    operation: *mut psa_cipher_operation_s,
) -> i32

Abort a cipher 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_cipher_encrypt_setup() or psa_cipher_decrypt_setup() again.

You may call this function any time after the operation object has been initialized as described in #psa_cipher_operation_t.

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

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

\retval #PSA_SUCCESS \emptydescription \retval #PSA_ERROR_COMMUNICATION_FAILURE \emptydescription \retval #PSA_ERROR_HARDWARE_FAILURE \emptydescription \retval #PSA_ERROR_CORRUPTION_DETECTED \emptydescription \retval #PSA_ERROR_BAD_STATE The library has not been previously initialized by psa_crypto_init(). It is implementation-dependent whether a failure to initialize results in this error code.
