    NAME

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

    SYNOPSIS

    #include <stdarg.h>
    #include <stdio.h>
    #include <wchar.h>
    
    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() respectively, except that instead of being called with a variable number of arguments, they are called with an argument list as defined by <stdarg.h>.

    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 attributes:

    SEE ALSO

    fwprintf(3C), setlocale(3C), attributes(5), standards(5)  

    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.
