/* Modified by Ruibiao Qiu <ruibiao@arl.wustl.edu,ruibiao@gmail.com>
|
|
* to add support for wide characters
|
|
* Changes:
|
|
* - Add a compiler variable HAVE_WCHAR for wide character only code
|
|
* - Add a pointer to liked list of non-spacing characters in __ldata
|
|
* and the macro to access the width field in the attribute field
|
|
* - Add a circular input character buffer in __screen to handle wide
|
|
* character input (used in get_wch())
