6 kcapi_aead_stream_op - obtain processed data (stream)

9 int32_t kcapi_aead_stream_op(struct kcapi_handle * handle,
10 struct iovec * iov, uint32_t iovlen);
11
13 handle
14 [in] cipher handle
15
16 iov
17 [out] scatter/gather list pointing to buffers to be filled with the
18 resulting data from a cipher operation.
19
20 iovlen
21 [in] number of outiov scatter/gather list elements.

24 This function may cause the caller to sleep if the kernel buffer
25 holding the data is empty. The process will be woken up once more data
26 is sent by calling kcapi_cipher_stream_update.
27
28 Note, when supplying buffers that are not multiple of block size, the
29 buffers will only be filled up to the maximum number of full block
30 sizes that fit into the buffer.
31
32 return number of bytes obtained from the kernel upon success; a
33 negative errno-style error code if an error occurred
