| Can anyone pls tell how to extract the last arguement from the variable argument list? | |

| Use va_end() for that. The va_end() function destroys the variable argument list pointer p, rendering it invalid unless va_start() is called again. |

| To access any elements we should av_arg(). va_end will return void so va_end is not used to extract last elements instead it used to destroy the va_list type ptr we created. |

| To extract the last argument we still need va_arg(), va_end() cleans up the list, it doesn't extract the last argument for us. | |
