4.23 fputws—write a wide character string in a file or stream

Synopsis

     #include <wchar.h>
     int fputws(const wchar_t *ws, FILE *fp);
     
     #include <wchar.h>
     int _fputws_r(struct _reent *ptr, const wchar_t *ws, FILE *fp);
     

Description
fputws writes the wide character string at ws (but without the trailing null) to the file or stream identified by fp.

_fputws_r is simply the reentrant version of fputws that takes an additional reentrant struct pointer argument: ptr.

Returns
If successful, the result is a non-negative integer; otherwise, the result is -1 to indicate an error.
