Print formatted wide-character output into a string
#include <wchar.h> int swprintf( wchar_t * ws, size_t n, const wchar_t * format, ... );
- A pointer to the buffer where you want to function to store the formatted string.
- The maximum number of wide characters to store in the buffer, including a terminating null character.
- 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() .
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The swprintf() function is similar to fwprintf() except that swprintf() places the generated output into the wide-character array pointed to by buf, instead of writing it to a file. A null character is placed at the end of the generated character string.
The swprintf() function is the wide-character version of sprintf() .
The number of wide characters written, excluding the terminating NUL, or a negative number if an error occurred ( errno is set).
|Signal handler||Read the Caveats|
It's safe to call this function in a signal handler if the data isn't floating point.
