Standard C Library Functions                        vfwprintf(3C)



NAME
     vfwprintf, vswprintf, vwprintf  -  wide-character  formatted
     output of a stdarg argument list

SYNOPSIS
     #include 
     #include 
     #include 

     int vfwprintf(FILE *restrict stream, const wchar_t *restrict format,
          va_list arg);


     int vswprintf(wchar_t *restrict s, size_t n,
          const wchar_t *restrict format, va_list arg);


     int vwprintf(const wchar_t *restrict format, va_list arg);


DESCRIPTION
     The vwprintf(), vfwprintf(), and vswprintf()  functions  are
     the  same  as  wprintf(), fwprintf(), and swprintf() respec-
     tively, except that instead of being called with a  variable
     number  of  arguments, they are called with an argument list
     as defined by  .


     These functions do not invoke the  va_end() macro.  However,
     as  these  functions do invoke the va_arg() macro, the value
     of ap after the return is indeterminate.

RETURN VALUES
     Refer to  fwprintf(3C).

ERRORS
     Refer to  fwprintf(3C).

USAGE
     Applications using these functions  should  call  va_end(ap)
     afterwards to clean up.

ATTRIBUTES
     See attributes(5) for descriptions of the  following  attri-

NOTES
     The vwprintf(), vfwprintf(), and vswprintf()  functions  can
     be  used  safely  in  multithreaded applications, as long as
     setlocale(3C) is not being called to change the locale.
