NAME
       usb_descriptor_fillbuf - fill buffer with descriptors

SYNOPSIS
       int usb_descriptor_fillbuf(void * buf, unsigned buflen, const struct usb_descriptor_header ** src);

ARGUMENTS
       buf
	   Buffer to be filled

       buflen
	   Size of buf

       src
	   Array of descriptor pointers, terminated by null pointer.

DESCRIPTION
       Copies descriptors into the buffer, returning the length or a negative error code if they can't all be copied. Useful when assembling

       need to be marshaled.
