getwchar

---

Reads a wide character from the standard input stream

 #include <wchar.h> wint_t getwchar( void ); 

The getwchar( ) function is the wide-character counterpart to getchar( ); it is equivalent to getwc( stdin ) and returns the wide character read. Like getwc( ), getwchar( ) may be implemented as a macro, but because it has no arguments, unforeseen side effects are not likely. A return value of WEOF indicates an error or an attempt to read past the end of the file. In these cases, the function sets the file's error or end-of-file flag as appropriate.

Example

 wint_t wc; if ( setlocale( LC_CTYPE, "" ) == NULL) {   fwprintf( stderr,             L"Sorry, couldn't change to the system's native locale.\n");   return 1; } while ( (wc = getwchar( )) != WEOF ) // or:  (wc = getwc( stdin)) {   wc = towupper(wc);   putwchar((wchar_t)wc);        // or:  putwc( (wchar_t)wc, stdout); }
