[PATCH 08/25] efi-stdio: return bytes actually consumed

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



efi_process_square_bracket() returns the number of characters consumed
including the escape character which starts the escape sequence. That
escape character is not passed to efi_process_square_bracket(), so it
seems more consistent to return the number of characters without the
escape.
