Defined in header
<cwchar>
std::wint_t fputwc( wchar_t ch, std::FILE * stream );
(1)
std::wint_t putwc( wchar_t ch, std::FILE * stream );
(2)
Writes a wide character ch to the given output stream stream.
2) May be implemented as a macro and may evaluate stream more than once.
Contents
[edit] Parameters
ch
-
wide character to be written
stream
-
the output stream
[edit] Return value
ch on success, WEOF on failure. If an encoding error occurs, errno is set to EILSEQ .
[edit] Example
Run this code
#include <cerrno> #include <clocale> #include <cstdio> #include <cstdlib> #include <cwchar> #include <initializer_list> int main() { std::setlocale (LC_ALL, "en_US.utf8"); for (const wchar_t ch : { L'\u2200', // Unicode name: "FOR ALL" L'\n', L'∀', }) { if (errno = 0; std::fputwc(ch, stdout) == WEOF) { std::puts (errno == EILSEQ ? "Encoding error in fputwc" : "I/O error in fputwc" ); return EXIT_FAILURE ; } } return EXIT_SUCCESS ; }
Possible output:
∀ ∀
