FPUTWS
NAME SYNOPSIS DESCRIPTION RETURN VALUE CONFORMING TO SEE ALSO NOTES
fputws - write a wide character string to a FILE stream
#include ws, FILE *stream);
The fputws function is the wide-character equivalent of the fputs function. It writes the wide character string starting at ws, up to but not including the terminating L'0' character, to stream.
The fputws function returns a nonnegative integer if the operation was successful, or -1 to indicate an error.
ISO/ANSI C, UNIX98
The behaviour of fputws depends on the LC_CTYPE category of the current locale.
In the absence of additional information passed to the fopen call, it is reasonable to expect that fputws will actually write the multibyte string corresponding to the wide character string ws.
