kcapi_akcipher_stream_init_sgn - start an signing operation (stream)
int32_t kcapi_akcipher_stream_init_sgn(struct kcapi_handle * handle, struct iovec * iov, uint32_t iovlen);
handle
iov
iovlen
A stream signing operation is started with this call. Multiple successive kcapi_akcipher_stream_update function calls can be invoked to send more plaintext data to be signed. The last invocation to supply data must be done with kcapi_akcipher_stream_update_last. The kernel buffers the input until kcapi_akcipher_stream_op picks up the signed data. Once plaintext is signed during the kcapi_cipher_stream_op it is removed from the kernel buffer.
The function calls of kcapi_akcipher_stream_update and kcapi_akcipher_stream_op can be mixed, even by multiple threads of an application.
return number of bytes sent to the kernel upon success; a negative errno-style error code if an error occurred
