NAME
       vscnprintf - Format a string and place it in a buffer

SYNOPSIS
       int vscnprintf(char * buf, size_t size, const char * fmt, va_list args);

ARGUMENTS
       buf
	   The buffer to place the result into

       size
	   The size of the buffer, including the trailing null space

       fmt
	   The format string to use

       args
	   Arguments for the format string

DESCRIPTION
       The return value is the number of characters which have been written into the buf not including the trailing ''. If size is <= 0 the
       function returns 0.

       Call this function if you are already dealing with a va_list. You probably want scnprintf instead.

       See the vsnprintf documentation for format string extensions over C99.
