getwc

---

Reads a wide character from a file

 #include <stdio.h> #include <wchar.h> wint_t getwc ( FILE *fp  ); 

The getwc( ) function is the wide-character counterpart to getc( ): it may be implemented as a macro, and may evaluate its argument more than once, causing unforeseen side effects. Use fgetwc( ) instead.

getwc( ) returns the character read. A return value of WEOF indicates an error or an attempt to read past the end of the file.

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 = getwc( stdin)) != WEOF ) {   wc = towupper(wc);   putwc( (wchar_t)wc, stdout); }
