usb_fill_int_urb(9)
NAME
usb_fill_int_urb - macro to help initialize a interrupt urb
SYNOPSIS
void usb_fill_int_urb(struct urb * urb, struct usb_device * dev,
unsigned int pipe, void * transfer_buffer,
int buffer_length, usb_complete_t complete_fn,
void * context, int interval);
ARGUMENTS
- urb
- pointer to the urb to initialize.
- dev
- pointer to the struct usb_device for this urb.
- pipe
- the endpoint pipe
- transfer_buffer
- pointer to the transfer buffer
- buffer_length
- length of the transfer buffer
- complete_fn
- pointer to the usb_complete_t function
- context
- what to set the urb context to.
- interval
- what to set the urb interval to, encoded like the endpoint
descriptor´s bInterval value.
DESCRIPTION
Initializes a interrupt urb with the proper information needed to
submit it to a device. Note that high speed interrupt endpoints use a
logarithmic encoding of the endpoint interval, and express polling
intervals in microframes (eight per millisecond) rather than in frames
(one per millisecond).
