GETWCHAR(3) Linux Programmer's Manual GETWCHAR(3) NAME getwchar - read a wide character from standard input 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 For an explanation of the terms used in this section, see attributes(7). ┌──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┬───────────────┬─────────┐ │Interface │ Attribute │ Value │ ├──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┼───────────────┼─────────┤ │getwchar() │ Thread safety │ MT-Safe │ └──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┴───────────────┴─────────┘ CONFORMING TO POSIX.1-2001, POSIX.1-2008, C99. 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.
