Function Documentation

nm_tactic_pack_ctrl()

static int nm_tactic_pack_ctrl ( nm_gate_t  p_gate, nm_drv_t p_drv   __attribute__(unused), struct nm_ctrl_chunk_s *  p_ctrl_chunk, struct nm_pkt_wrap_s *  p_pw  )

inlinestatic

Try to pack a control chunk in a pw.

Returns

NM_ESUCCESS for success, -NM_EBUSY if pw full

Note

function takes ownership of p_ctrl_chunk
