+ * vscnprintf - Format a string and place it in a buffer
+ * @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
+ *
+ * The return value is the number of characters which have been written into
+ * the @buf not including the trailing '\0'. If @size is == 0 the function
+ * returns 0.
+ *
+ * If you're not already dealing with a va_list consider using scnprintf().
+ *
+ * See the vsnprintf() documentation for format string extensions over C99.
