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, 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: 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).
