Detailed Description

A Timeout is used to call a function at a point in the future.

You can use as many seperate Timeout objects as you require.

Example:

 // Blink until timeout.

 #include "mbed.h"

 Timeout timeout;
 DigitalOut led(LED1);

 int on = 1;

 void attimeout() {
     on = 0;
 }

 int main() {
     timeout.attach(&attimeout, 5);
     while(on) {
         led = !led;
         wait(0.2);
     }
 }
