emilmont 10:3bc89ef62ce7 19 /** To generate a fatal compile-time error, you can use the pre-processor #error directive.
emilmont 10:3bc89ef62ce7 20 *
emilmont 10:3bc89ef62ce7 21 * @code
emilmont 10:3bc89ef62ce7 22 * #error "That shouldn't have happened!"

emilmont 10:3bc89ef62ce7 24 *
emilmont 10:3bc89ef62ce7 25 * If the compiler evaluates this line, it will report the error and stop the compile.
emilmont 10:3bc89ef62ce7 26 *
emilmont 10:3bc89ef62ce7 27 * For example, you could use this to check some user-defined compile-time variables:
emilmont 10:3bc89ef62ce7 28 *
emilmont 10:3bc89ef62ce7 29 * @code
emilmont 10:3bc89ef62ce7 30 * #define NUM_PORTS 7
emilmont 10:3bc89ef62ce7 31 * #if (NUM_PORTS > 4)
emilmont 10:3bc89ef62ce7 32 * #error "NUM_PORTS must be less than 4"
emilmont 10:3bc89ef62ce7 33 * #endif
emilmont 10:3bc89ef62ce7 34 * @endcode
emilmont 10:3bc89ef62ce7 35 *
emilmont 10:3bc89ef62ce7 36 * Reporting Run-Time Errors:
emilmont 10:3bc89ef62ce7 37 * To generate a fatal run-time error, you can use the mbed error() function.
emilmont 10:3bc89ef62ce7 38 *
emilmont 10:3bc89ef62ce7 39 * @code
emilmont 10:3bc89ef62ce7 40 * error("That shouldn't have happened!");
emilmont 10:3bc89ef62ce7 41 * @endcode
emilmont 10:3bc89ef62ce7 42 *
emilmont 10:3bc89ef62ce7 43 * If the mbed running the program executes this function, it will print the
emilmont 10:3bc89ef62ce7 44 * message via the USB serial port, and then die with the blue lights of death!
emilmont 10:3bc89ef62ce7 45 *
emilmont 10:3bc89ef62ce7 46 * The message can use printf-style formatting, so you can report variables in the
emilmont 10:3bc89ef62ce7 47 * message too. For example, you could use this to check a run-time condition:
emilmont 10:3bc89ef62ce7 48 *
emilmont 10:3bc89ef62ce7 49 * @code
emilmont 10:3bc89ef62ce7 50 * if(x >= 5) {
emilmont 10:3bc89ef62ce7 51 * error("expected x to be less than 5, but got %d", x);
emilmont 10:3bc89ef62ce7 52 * }
emilmont 10:3bc89ef62ce7 53 * #endcode
