getwchar - read a wide character from standard inputLibrary
Standard C library ( libc ", " -lc )Synopsis
#include <wchar.h> "wint_t getwchar(void);"
Description
The getwchar() function is the wide-character equivalent of the getchar(3) function. It reads a wide character from stdin and returns it. If the end of stream is reached, or if ferror(stdin) becomes true, it returns WEOF .If a wide-character conversion error occurs, it sets errno to EILSEQ and returns WEOF .For a nonlocking counterpart, see unlocked_stdio(3).
Return Value
The getwchar() function returns the next wide-character from standard input, or WEOF .Attributes

C11, POSIX.1-2008.History
C99, POSIX.1-2001.Notes
The behavior of getwchar() depends on the LC_CTYPE category of the current locale.It is reasonable to expect that getwchar() will actually read a multibyte sequence from standard input and then convert it to a wide character.
