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
       descriptors  for  an  associated  set  of  interfaces  used  as part of
       configuring a composite  device;  or  in  other  cases  where  sets  of
       descriptors need to be marshaled.
