Done.

Return success even if there were no radios?

[gogerald1, 2016/02/08 17:00:04]

Done. Move error record from next CL to this CL.

If no radios it seems that FALSE should be returned?

Done.

There is very likely a src/base utility for this, most likely:
vswprintf in src/base/strings/string_util_win.h.

[gogerald1, 2016/02/08 17:00:04]

It looks this function is used to write formatted data from variable argument
list (va_list) to sized buffer, but not string16 input. Instead I use wcsncpy to
make it look neat.
