rolf.meyer@arm.com 11:1c1ebd0324fa 27 * For example, you could use this to check some user-defined compile-time variables:

rolf.meyer@arm.com 11:1c1ebd0324fa 36 * Reporting Run-Time Errors:
rolf.meyer@arm.com 11:1c1ebd0324fa 37 * To generate a fatal run-time error, you can use the mbed error() function.
rolf.meyer@arm.com 11:1c1ebd0324fa 38 *
emilmont 43:e2ed12d17f06 39 * @code
emilmont 43:e2ed12d17f06 40 * error("That shouldn't have happened!");
emilmont 43:e2ed12d17f06 41 * @endcode
rolf.meyer@arm.com 11:1c1ebd0324fa 42 *
emilmont 55:d722ed6a4237 43 * If the mbed running the program executes this function, it will print the
rolf.meyer@arm.com 11:1c1ebd0324fa 44 * message via the USB serial port, and then die with the blue lights of death!
rolf.meyer@arm.com 11:1c1ebd0324fa 45 *
emilmont 55:d722ed6a4237 46 * The message can use printf-style formatting, so you can report variables in the
rolf.meyer@arm.com 11:1c1ebd0324fa 47 * message too. For example, you could use this to check a run-time condition:
emilmont 55:d722ed6a4237 48 *
emilmont 43:e2ed12d17f06 49 * @code
emilmont 43:e2ed12d17f06 50 * if(x >= 5) {
emilmont 43:e2ed12d17f06 51 * error("expected x to be less than 5, but got %d", x);
emilmont 43:e2ed12d17f06 52 * }
