fputws(3) Library Functions Manual fputws(3) NAME fputws - write a wide-character string to a FILE stream LIBRARY Standard C library (libc, -lc) 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 at- tributes(7). ┌────────────────────────────────────────────┬───────────────┬─────────┐ │Interface │ Attribute │ Value │ ├────────────────────────────────────────────┼───────────────┼─────────┤ │fputws() │ Thread safety │ MT-Safe │ └────────────────────────────────────────────┴───────────────┴─────────┘ STANDARDS POSIX.1-2001, POSIX.1-2008, C99. NOTES The behavior of fputws() depends on the LC_CTYPE category of the cur- rent locale. In the absence of additional information passed to the fopen(3) call, it is reasonable to expect that fputws() will actually write the multi- byte string corresponding to the wide-character string ws.
