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.
[edit] Parameters ch - wide character to be written stream - the output stream [edit] Return valuech on success, WEOF on failure. If an encoding error occurs, errno is set to EILSEQ.
[edit] Example#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'â', }) { 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; }
