vwprintf()

Write formatted output to standard output (varargs)

Synopsis:

#include <wchar.h>
#include <stdarg.h>

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

Arguments:

format

A wide-character string that specifies the format of the output. The formatting string determines what additional arguments you need to provide. For more information, see printf().

arg

A variable-argument list of the additional arguments, which you must have initialized with the va_start() macro.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The vwprintf() function writes output to the file stdout, under control of the argument format.

The vwprint() function is the wide-character version of vprintf(), and is a "varargs" version of wprintf().

Returns:

The number of characters written, or a negative value if an output error occurred (errno is set).

Classification:

ANSI, POSIX 1003.1

Safety:
Cancellation point	No
Interrupt handler	No
Signal handler	No
Thread	Yes
