  16 .TH FPUTWS 3  2019-03-06 "GNU" "Linux Programmer's Manual"
  17 .SH NAME
  18 fputws \- write a wide-character string to a FILE stream
  19 .SH SYNOPSIS
  20 .nf
  21 .B #include <wchar.h>
  22 .PP
  23 .BI "int fputws(const wchar_t *" ws ", FILE *" stream );
  24 .fi
  25 .SH DESCRIPTION
  26 The
  27 .BR fputws ()
  28 function is the wide-character equivalent of
  29 the
  30 .BR fputs (3)
  31 function.
  32 It writes the wide-character string starting at \fIws\fP, up to but
  33 not including the terminating null wide character (L\(aq\e0\(aq), to \fIstream\fP.
  34 .PP
  35 For a nonlocking counterpart, see
  36 .BR unlocked_stdio (3).
  37 .SH RETURN VALUE
  38 The
  39 .BR fputws ()
  40 function returns a
  41 nonnegative integer if the operation was
  42 successful, or \-1 to indicate an error.
  43 .SH ATTRIBUTES

  58 .SH NOTES
  59 The behavior of
  60 .BR fputws ()
  61 depends on the
  62 .B LC_CTYPE
  63 category of the
  64 current locale.
  65 .PP
  66 In the absence of additional information passed to the
  67 .BR fopen (3)
  68 call, it is
  69 reasonable to expect that
  70 .BR fputws ()
  71 will actually write the multibyte
  72 string corresponding to the wide-character string \fIws\fP.
