NAMEfputws - write a wide-character string to a FILE stream
#include <wchar.h> int fputws(const wchar_t *ws, FILE *stream);
DESCRIPTIONThe fputws() function is the wide-character equivalent of the fputs(3) function. It writes the wide-character string starting at ws, up to but not including the terminating L'\0' character, to stream.
For a non-locking counterpart, see unlocked_stdio(3).
RETURN VALUEThe fputws() function returns a non-negative integer if the operation was successful, or -1 to indicate an error.
CONFORMING TOC99, POSIX.1-2001.
NOTESThe behavior of fputws() depends on the LC_CTYPE category of the current locale.
In the absence of additional information passed to the fopen(3) call, it is reasonable to expect that fputws() will actually write the multibyte string corresponding to the wide-character string ws.
