|
|
*Purpose:
|
|
* defines _putwch() - writes a wide character to a console
|
|
*
|
|
*Revision History:
|
|
* 02-11-00 GB Module Created.
|
|
* 04-25-00 GB Made putwch more robust in using WriteConsoleW
|
|
* 05-17-00 GB Use ERROR_CALL_NOT_IMPLEMENTED for existance of W API
|
|
* 11-22-00 PML Wide-char *putwc* functions take a wchar_t, not wint_t.
