SYNOPSIS

10       int usb_find_common_endpoints_reverse(struct usb_host_interface * alt,
11                                             struct usb_endpoint_descriptor ** bulk_in,
12                                             struct usb_endpoint_descriptor ** bulk_out,
13                                             struct usb_endpoint_descriptor ** int_in,
14                                             struct usb_endpoint_descriptor ** int_out);

ARGUMENTS

17       alt
18           alternate setting to search
19
20       bulk_in
21           pointer to descriptor pointer, or NULL
22
23       bulk_out
24           pointer to descriptor pointer, or NULL
25
26       int_in
27           pointer to descriptor pointer, or NULL
28
29       int_out
30           pointer to descriptor pointer, or NULL
31

DESCRIPTION

33       Search the alternate setting's endpoint descriptors for the last
34       bulk-in, bulk-out, interrupt-in and interrupt-out endpoints and return
35       them in the provided pointers (unless they are NULL).
36
37       If a requested endpoint is not found, the corresponding pointer is set
38       to NULL.
39

RETURN

41       Zero if all requested descriptors were found, or -ENXIO otherwise.
