Converts a wide character to its corresponding multibyte value, and
writes the result to a specified file.
Format
#include <wchar.h>
wint_t putwc (wint_t wc, FILE *file_ptr);
Arguments
- wc
- An object of type wint_t.
- file_ptr
- A file pointer.
Description
Since putwc might be implemented as a macro, a file pointer
argument with side effects (for example putwc (wc, *f++)) might
be evaluated incorrectly. In such a case, use the fputwc function
instead. See also fputwc in this section.
Return Values
| x | The character written to the file.
Indicates success. |
| WEOF |
Indicates an output error. The function sets errno. For a
list of the errno values set by this function, see fputwc in this
section. |
