.SH "DESCRIPTION"
.PP
This function is called in interrupt context only\&. If the reply reached before the timeout, the i2o_exec_wait struct is filled with the message and the task will be waked up\&. The task is now responsible for returning the message m back to the controller! If the message reaches us after the timeout clean up the i2o_exec_wait struct (including allocated DMA buffer)\&.
.PP
Return 0 on success and if the message m should not be given back to the I2O controller, or >0 on success and if the message should be given back afterwords\&. Returns negative error code on failure\&. In this case the message must also be given back to the controller\&.
