+A reference to a communication identifier where the request 
+will be posted.
+.IP "context" 12
+User-defined context associated with the request.

+written into the remote memory region.
+.SH "RETURN VALUE"
+Returns 0 on success, or -1 on error.  If an error occurs, errno will be
+set to indicate the failure reason.
+.SH "NOTES"
+For a list of supported flags, see ibv_post_send.  Unless inline
+data is specified, the local data buffers must have been registered
+before the write is issued, and the buffers must remain registered
+until the write completes.  The remote buffers must always be registered.

+Write operations may not be posted to an rdma_cm_id or the corresponding
+queue pair until it has been connected.

+The user-defined context associated with the write request will be
+returned to the user through the work completion wr_id, work request
+identifier, field.
