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); |
struct usb_composite_dev * cdevthe device whose string descriptor IDs are being allocated and attached.
struct usb_gadget_strings ** span array of usb_gadget_strings to attach.
unsigned n_stringsnumber 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 languages 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 contains the translation of the first usb_string entry of en-US. Therefore both entries become the same id assign.
