mbotkinl 0:2cc6bb4d7fea 19 /** To generate a fatal compile-time error, you can use the pre-processor #error directive.
mbotkinl 0:2cc6bb4d7fea 20 *
mbotkinl 0:2cc6bb4d7fea 21 * @code
mbotkinl 0:2cc6bb4d7fea 22 * #error "That shouldn't have happened!"

mbotkinl 0:2cc6bb4d7fea 25 * If the compiler evaluates this line, it will report the error and stop the compile.
mbotkinl 0:2cc6bb4d7fea 26 *
mbotkinl 0:2cc6bb4d7fea 27 * For example, you could use this to check some user-defined compile-time variables:
mbotkinl 0:2cc6bb4d7fea 28 *
mbotkinl 0:2cc6bb4d7fea 29 * @code
mbotkinl 0:2cc6bb4d7fea 30 * #define NUM_PORTS 7
mbotkinl 0:2cc6bb4d7fea 31 * #if (NUM_PORTS > 4)
mbotkinl 0:2cc6bb4d7fea 32 * #error "NUM_PORTS must be less than 4"
mbotkinl 0:2cc6bb4d7fea 33 * #endif
mbotkinl 0:2cc6bb4d7fea 34 * @endcode
mbotkinl 0:2cc6bb4d7fea 35 *
mbotkinl 0:2cc6bb4d7fea 36 * Reporting Run-Time Errors:
mbotkinl 0:2cc6bb4d7fea 37 * To generate a fatal run-time error, you can use the mbed error() function.
mbotkinl 0:2cc6bb4d7fea 38 *
mbotkinl 0:2cc6bb4d7fea 39 * @code
mbotkinl 0:2cc6bb4d7fea 40 * error("That shouldn't have happened!");
mbotkinl 0:2cc6bb4d7fea 41 * @endcode
mbotkinl 0:2cc6bb4d7fea 42 *
mbotkinl 0:2cc6bb4d7fea 43 * If the mbed running the program executes this function, it will print the
mbotkinl 0:2cc6bb4d7fea 44 * message via the USB serial port, and then die with the blue lights of death!
mbotkinl 0:2cc6bb4d7fea 45 *
mbotkinl 0:2cc6bb4d7fea 46 * The message can use printf-style formatting, so you can report variables in the
mbotkinl 0:2cc6bb4d7fea 47 * message too. For example, you could use this to check a run-time condition:
mbotkinl 0:2cc6bb4d7fea 48 *
mbotkinl 0:2cc6bb4d7fea 49 * @code
mbotkinl 0:2cc6bb4d7fea 50 * if(x >= 5) {
mbotkinl 0:2cc6bb4d7fea 51 * error("expected x to be less than 5, but got %d", x);
mbotkinl 0:2cc6bb4d7fea 52 * }
mbotkinl 0:2cc6bb4d7fea 53 * #endcode
