+/**
+ * The passthru function is similar to the
+ * exec function in that it executes a
+ * command. This function
+ * should be used in place of exec or
+ * system when the output from the Unix command
+ * is binary data which needs to be passed directly back to the
+ * browser.  A common use for this is to execute something like the
+ * pbmplus utilities that can output an image stream directly.  By
+ * setting the Content-type to image/gif and
+ * then calling a pbmplus program to output a gif, you can create
+ * PHP scripts that output images directly.
+ *
+ * @param string $command The command that will be executed.
+ * @param int|null $result_code If the result_code argument is present, the
+ * return status of the Unix command will be placed here.
+ * @throws ExecException
