/* 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()) |
