/**
* Encrypts or sign the data.
*
* There can only be one GSS_IOV_BUFFER_TYPE_DATA buffer.
* There can be as 0 or more GSS_IOV_BUFFER_TYPE_SIGN_ONLY buffers.
* The maximum packet size is gss_context_stream_sizes.max_msg_size.
*
* The caller needs provide either:
* The caller needs provide the folloing buffers:
*
* - one GSS_IOV_BUFFER_TYPE_HEADER, one GSS_IOV_BUFFER_TYPE_PADDING, andd one GSS_IOV_BUFFER_TYPE_TRAILER
* - on DCE-RPC mode, only one GSS_IOV_BUFFER_TYPE_HEADER may be given
* - HEADER (of size gss_context_stream_sizes.header)
* SIGN_ONLY (optional, zero or more)
* DATA
* SIGN_ONLY (optional, zero or more)
* PADDING (of size gss_context_stream_sizes.blocksize)
* TRAILER (of size gss_context_stream_sizes.trailer)
*
* To generate gss_wrap() comptaible headers, use: HEADER | DATA | PADDING | TRAILER
* - on DCE-RPC mode, the caller can skip PADDING and TRAILER if the
* DATA elements is padded to a block bountry.
*
* To generate gss_wrap() compatible packets, use: HEADER | DATA | PADDING | TRAILER
*
* The input sizes of HEADER, PADDING and TRAILER can be fetched using gss_wrap_iov_length() or
* gss_context_query_attributes().
