USB_GSTRINGS_ATTACH(9) Kernel Mode Gadget API USB_GSTRINGS_ATTACH(9)NAMEusb_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 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.
