USB_COPY_DESCRIPTORS(9) 				      Kernel Mode Gadget API					   USB_COPY_DESCRIPTORS(9)

NAME
       usb_copy_descriptors - copy a vector of USB descriptors

SYNOPSIS
       struct usb_descriptor_header ** usb_copy_descriptors(struct usb_descriptor_header ** src);

ARGUMENTS
       src
	   null-terminated vector to copy

CONTEXT
       initialization code, which may sleep

DESCRIPTION
       This makes a copy of a vector of USB descriptors. Its primary use is to support usb_function objects which can have multiple copies, each
       needing different descriptors. Functions may have static tables of descriptors, which are used as templates and customized with identifiers
       (for interfaces, strings, endpoints, and more) as needed by a given function instance.
