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 wchart *restrict format,
          valist arg);


     int vswprintf(wchart *restrict s, sizet n,
          const wchart *restrict format, valist arg);


     int vwprintf(const wchart *restrict format, valist 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  vaend() macro.  However,
     as  these  functions do invoke the vaarg() macro, the value
     of ap after the return is indeterminate.

RETURN VALUES
     Refer to  fwprintf(3C).

ERORS
     Refer to  fwprintf(3C).

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

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.
