USB_STRING_IDS_N(9) Kernel Mode Gadget API USB_STRING_IDS_N(9)NAME
usb_string_ids_n - allocate unused string IDs in batch
int usb_string_ids_n(struct usb_composite_dev * c, unsigned n);
the device whose string descriptor IDs are being allocated
number of string IDs to allocate
single threaded during gadget setup
Returns the first requested ID. This ID and next n-1 IDs are now valid IDs. At least provided that n is non-zero because if it is, returns
last requested ID which is now very useful information.
usb_string_ids_n() is called from bind callbacks to allocate string IDs. Drivers for functions, configurations, or gadgets will then store
that ID in the appropriate descriptors and string table.
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.

USB_GSTRINGS_ATTACH(9) Kernel Mode Gadget API USB_GSTRINGS_ATTACH(9)NAME
usb_gstrings_attach - attach gadget strings to a cdev and assign ids
struct usb_string * usb_gstrings_attach(struct usb_composite_dev * cdev, struct usb_gadget_strings ** sp, unsigned n_strings);
the device whose string descriptor IDs are being allocated and attached.
an array of usb_gadget_strings to attach.
number of entries in each usb_strings array (sp->strings)
This function will create a deep copy of usb_gadget_strings and usb_string and attach it to the cdev. The actual string (usb_string.s) will
not be copied but only a referenced will be made. The struct usb_gadget_strings array may contain multiple languges and should be NULL
terminated. The ->language pointer of each struct usb_gadget_strings has to contain the same amount of entries.
sp is en-US, sp is es-ES. It is expected that the first usb_string entry of es-ES containts the translation of the first usb_string
entry of en-US. Therefore both entries become the same id assign.
