I2O_MSG_GET(9)		     Message-based devices		I2O_MSG_GET(9)

NAME
       i2o_msg_get - obtain an I2O message from the IOP

SYNOPSIS
       struct i2o_message * i2o_msg_get(struct i2o_controller * c);

ARGUMENTS
       c
	   I2O controller

DESCRIPTION
       This function tries to get a message frame. If no message frame is
       available do not wait until one is availabe (see also
       i2o_msg_get_wait). The returned pointer to the message frame is not in
       I/O memory, it is allocated from a mempool. But because a MFA is
       allocated from the controller too it is guaranteed that i2o_msg_post
       will never fail.

       On a success a pointer to the message frame is returned. If the message
       queue is empty -EBUSY is returned and if no memory is available -ENOMEM
       is returned.
