USB_STRING_IDS_TAB(9) Kernel Mode Gadget API USB_STRING_IDS_TAB(9)NAMEusb_string_ids_tab - allocate unused string IDs in batch
SYNOPSIS
int usb_string_ids_tab(struct usb_composite_dev * cdev,
struct usb_string * str);
ARGUMENTS
cdev
the device whose string descriptor IDs are being allocated
str
an array of usb_string objects to assign numbers to
CONTEXT
single threaded during gadget setup
DESCRIPTIONusb_string_ids() is called from bind callbacks to allocate string IDs.
Drivers for functions, configurations, or gadgets will then copy IDs
from the string table to the appropriate descriptors and string table
for other languages.
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.
