gkroussos 0:637031152314 20 *
gkroussos 0:637031152314 21 * @code
gkroussos 0:637031152314 22 * #error "That shouldn't have happened!"
gkroussos 0:637031152314 23 * @endcode
gkroussos 0:637031152314 24 *
gkroussos 0:637031152314 25 * If the compiler evaluates this line, it will report the error and stop the compile.
gkroussos 0:637031152314 26 *
gkroussos 0:637031152314 27 * For example, you could use this to check some user-defined compile-time variables:
gkroussos 0:637031152314 28 *
gkroussos 0:637031152314 29 * @code
gkroussos 0:637031152314 30 * #define NUM_PORTS 7
gkroussos 0:637031152314 31 * #if (NUM_PORTS > 4)
gkroussos 0:637031152314 32 * #error "NUM_PORTS must be less than 4"
gkroussos 0:637031152314 33 * #endif
gkroussos 0:637031152314 34 * @endcode
gkroussos 0:637031152314 35 *
gkroussos 0:637031152314 36 * Reporting Run-Time Errors:
gkroussos 0:637031152314 37 * To generate a fatal run-time error, you can use the mbed error() function.
gkroussos 0:637031152314 38 *
gkroussos 0:637031152314 39 * @code
gkroussos 0:637031152314 40 * error("That shouldn't have happened!");
gkroussos 0:637031152314 41 * @endcode
gkroussos 0:637031152314 42 *
gkroussos 0:637031152314 43 * If the mbed running the program executes this function, it will print the
gkroussos 0:637031152314 44 * message via the USB serial port, and then die with the blue lights of death!
gkroussos 0:637031152314 45 *
gkroussos 0:637031152314 46 * The message can use printf-style formatting, so you can report variables in the
gkroussos 0:637031152314 47 * message too. For example, you could use this to check a run-time condition:
gkroussos 0:637031152314 48 *
gkroussos 0:637031152314 49 * @code
gkroussos 0:637031152314 50 * if(x >= 5) {
gkroussos 0:637031152314 51 * error("expected x to be less than 5, but got %d", x);
gkroussos 0:637031152314 52 * }
gkroussos 0:637031152314 53 * #endcode
