USB_STRING_IDS_TAB(9)                 Kernel Mode Gadget API                USB_STRING_IDS_TAB(9)



NAME
       usb_string_ids_tab - allocate unused string IDs in batch

SYNOPSIS
       int usb_string_ids_tab(struct usb_composite_dev * cdev, struct usb_string * str);

ARGUMENTS
       cdev
           the device whose string descriptor IDs are being allocated

       str
           an array of usb_string objects to assign numbers to

CONTEXT
       single threaded during gadget setup

DESCRIPTION
       usb_string_ids() is called from bind callbacks to allocate string IDs. Drivers for
       functions, configurations, or gadgets will then copy IDs from the string table to the
       appropriate descriptors and string table for other languages.

       All string identifier should be allocated using this, usb_string_id() or
       usb_string_ids_n() routine, to ensure that for example different functions don't wrongly
       assign different meanings to the same identifier.
