Name

usb_gstrings_attach — attach gadget strings to a cdev and assign ids

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 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.
