NAME
       i2o_msg_post_wait_mem - Post and wait a message with DMA buffers

SYNOPSIS
       int i2o_msg_post_wait_mem(struct i2o_controller * c,
				 struct i2o_message * msg,
				 unsigned long timeout, struct i2o_dma * dma);

ARGUMENTS
       c
	   controller

       msg
	   message to post

       timeout
	   time in seconds to wait

       dma
	   i2o_dma struct of the DMA buffer to free on failure

DESCRIPTION
       This API allows an OSM to post a message and then be told whether or
       not the system received a successful reply. If the message times out
       then the value ´-ETIMEDOUT´ is returned. This is a special case. In
       this situation the message may (should) complete at an indefinite time
       in the future. When it completes it will use the memory buffer attached
       to the request. If -ETIMEDOUT is returned then the memory buffer must
       not be freed. Instead the event completion will free them for you. In
       all other cases the buffer are your problem.

       Returns 0 on success, negative error code on timeout or positive error
       code from reply.
