usb_pipe_get_state(9f)

usb_pipe_get_state(9F)         Kernel Functions         usb_pipe_get_state(9F)



NAME
       usb_pipe_get_state - Return USB pipe state

SYNOPSIS
       #include <sys/usb/usba.h>

       int usb_pipe_get_state(usb_pipe_handle_t pipe_handle,
            usb_pipe_state_t *pipe_state, usb_flags_t usb_flags);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI)

PARAMETERS
       pipe_handle    Handle of the pipe to retrieve the state.


       pipe_state     Pointer to where pipe state is returned.


       usb_flags      No flags are recognized. Reserved for future expansion.


DESCRIPTION
       The  usb_pipe_get_state()  function  retrieves  the  state  of the pipe
       referred to by pipe_handle into the location pointed to by pipe_state.


       Possible pipe states are:

       USB_PIPE_STATE_CLOSED     Pipe is closed.


       USB_PIPE_STATE_ACTIVE     Pipe is active  and  can  send/receive  data.
                                 Polling  is active for isochronous and inter‐
                                 rupt pipes.


       USB_PIPE_STATE_IDLE       Polling is stopped for isochronous and inter‐
                                 rupt-IN pipes.


       USB_PIPE_STATE_ERROR      An   error   occurred.   Client   must   call
                                 usb_pipe_reset(). Note that  this  status  is
                                 not    seen    by    a   client   driver   if
                                 USB_ATTRS_AUTOCLEARING is set in the  request
                                 attributes.


       USB_PIPE_STATE_CLOSING    Pipe  is  being  closed.  Requests  are being
                                 drained from the pipe and other cleanup is in
                                 progress.


RETURN VALUES
       USB_SUCCESS         Pipe state returned in second argument.


       USB_INVALID_ARGS    Pipe_state argument is NULL.


       USB_INVALID_PIPE    Pipe_handle argument is NULL.


CONTEXT
       May be called from user, kernel or interrupt context.

EXAMPLES
             usb_pipe_handle_t pipe;
             usb_pipe_state_t state;

             /* Recover if the pipe is in an error state. */
             if ((usb_pipe_get_state(pipe, &state, 0) == USB_SUCCESS) &&
                 (state == USB_PIPE_STATE_ERROR)) {
                     cmn_err (CE_WARN, "%s%d: USB Pipe error.",
                         ddi_driver_name(dip), ddi_get_instance(dip));
                     do_recovery();
             }
