NAME¶
usb_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
DESCRIPTION¶
usb_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.
