FPUTWS(3) Linux Programmer's Manual FPUTWS(3) NAME fputws - write a wide-character string to a FILE stream SYNOPSIS #include <wchar.h> int fputws(const wchar_t *restrict ws, FILE *restrict stream); DESCRIPTION The 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 null wide character (L'\0'), to stream. For a nonlocking counterpart, see unlocked_stdio(3). RETURN VALUE The fputws() function returns a nonnegative integer if the operation was successful, or -1 to indicate an error. ATTRIBUTES For an explanation of the terms used in this section, see attributes(7). ┌──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┬───────────────┬─────────┐ │Interface │ Attribute │ Value │ ├──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┼───────────────┼─────────┤ │fputws() │ Thread safety │ MT-Safe │ └──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┴───────────────┴─────────┘ CONFORMING TO POSIX.1-2001, POSIX.1-2008, C99. NOTES The 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 corre‐ sponding to the wide-character string ws.
