May be implemented as a macro and may evaluate
stream
more than once.
Parameters
| ch | - | wide character to be written |
| stream | - | the output stream |
Return value
Returns a copy of ch on success.
On failure, returns WEOF and sets the error indicator (see ferror() ) on stream .
If an encoding error occurred, additionally sets errno to EILSEQ .
Example
Run this code
#include <errno.h> #include <locale.h> #include <stdio.h> #include <stdlib.h> #include <wchar.h> int main(void) { setlocale(LC_ALL, "en_US.utf8"); errno = 0; if (fputwc(L'🍌', stdout) == WEOF) { if (errno == EILSEQ) puts("Encoding error in fputwc."); else puts("I/O error in fputwc."); return EXIT_FAILURE; } }
Possible output:
🍌
