int putws(wchar_t *s);
The putws() function converts the Process Code string (terminated by a (wchar_t)NULL) pointed to by s, to an Extended Unix Code (EUC) string followed by a NEWLINE character, and writes it to the standard output stream stdout. It does not write the terminal null character.
The putws() function returns the number of Process Code characters transformed and written. It returns EOF if it attempts to write to a file that has not been opened for writing.
