[libusb] libusb cancel transfer

[Phani K. <pha...@gm...>]

Hi

If application is killed by CTRL + C, then close is called on the open
devices.
In do_close (in core.c), which is called from libusb_close, we are going
through the in-flight transfer list and deleting them. Why abort
(libusb_cancel_transfer) is not called from the libusb library on those
transfers as they might be pending with driver?

Is it driver/respective platform's  job to abort those inflight transfers
when close is called on them or
why not library take care of it by calling libusb_cancel_transfer while it
doing close on device?

Kindly clarify.

Regards
Phani
