SYNOPSIS
- struct usb_string * usb_gstrings_attach(struct usb_composite_dev * cdev, struct usb_gadget_strings ** sp, unsigned n_strings);
ARGUMENTS
cdev
-
- the device whose string descriptor IDs are being allocated and attached.
sp
- an array of usb_gadget_strings to attach.
n_strings
- number of entries in each usb_strings array (sp[]->strings)
DESCRIPTION
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.
FOR INSTANCE
sp[0] is en-US, sp[1] 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.
