NAME¶

struct_usb_sg_request - support for scatter/gather I/O

SYNOPSIS¶

struct usb_sg_request {


  int status;


  size_t bytes;
};  

MEMBERS¶

status

bytes

DESCRIPTION¶

These requests are initialized using usb_sg_init, and then are used as request handles passed to usb_sg_wait or usb_sg_cancel. Most members of the request object aren´t for driver access.

The status and bytecount values are valid only after usb_sg_wait returns. If the status is zero, then the bytecount matches the total from the request.

After an error completion, drivers may need to clear a halt condition on the endpoint.
