VFWPRINTF(3)

NAME
4.70 `vfwprintf', `vwprintf', `vswprintf'--wide character format argument list

SYNOPSIS
     #include <stdio.h>
     #include <stdarg.h>
     #include <wchar.h>
     int vwprintf(const wchar_t *FMT, va_list LIST);
     int vfwprintf(FILE *FP, const wchar_t *FMT, va_list LIST);
     int vswprintf(wchar_t *STR, size_t SIZE, const wchar_t *FMT,
         va_list LIST);
     int _vwprintf_r(struct _reent *REENT, const wchar_t *FMT,
         va_list LIST);
     int _vfwprintf_r(struct _reent *REENT, FILE *FP,
         const wchar_t *FMT, va_list LIST);
     int _vswprintf_r(struct _reent *REENT, wchar_t *STR,
         size_t SIZE, const wchar_t *FMT, va_list LIST);

DESCRIPTION
`vwprintf', `vfwprintf' and `vswprintf' are (respectively) variants of `wprintf', `fwprintf' and `swprintf'. They differ only in allowing their caller to pass the variable argument list as a `va_list' object (initialized by `va_start') rather than directly accepting a variable number of arguments. The caller is responsible for calling `va_end'.
   `_vwprintf_r', `_vfwprintf_r' and `_vswprintf_r' are reentrant versions of the above.

RETURNS
The return values are consistent with the corresponding functions.

PORTABILITY
POSIX-1.2008 with extensions; C99 (compliant except for POSIX extensions).
   Supporting OS subroutines required: `close', `fstat', `isatty', `lseek', `read', `sbrk', `write'. *See Also*
`wprintf', `fwprintf' and `swprintf'.
