phungductung 0:e87aa4c49e95 19 /** To generate a fatal compile-time error, you can use the pre-processor #error directive.
phungductung 0:e87aa4c49e95 20 *
phungductung 0:e87aa4c49e95 21 * @code
phungductung 0:e87aa4c49e95 22 * #error "That shouldn't have happened!"
phungductung 0:e87aa4c49e95 23 * @endcode
phungductung 0:e87aa4c49e95 24 *
phungductung 0:e87aa4c49e95 25 * If the compiler evaluates this line, it will report the error and stop the compile.
phungductung 0:e87aa4c49e95 26 *
phungductung 0:e87aa4c49e95 27 * For example, you could use this to check some user-defined compile-time variables:
phungductung 0:e87aa4c49e95 28 *
phungductung 0:e87aa4c49e95 29 * @code
phungductung 0:e87aa4c49e95 30 * #define NUM_PORTS 7
phungductung 0:e87aa4c49e95 31 * #if (NUM_PORTS > 4)
phungductung 0:e87aa4c49e95 32 * #error "NUM_PORTS must be less than 4"
phungductung 0:e87aa4c49e95 33 * #endif
phungductung 0:e87aa4c49e95 34 * @endcode
phungductung 0:e87aa4c49e95 35 *
phungductung 0:e87aa4c49e95 36 * Reporting Run-Time Errors:
phungductung 0:e87aa4c49e95 37 * To generate a fatal run-time error, you can use the mbed error() function.
phungductung 0:e87aa4c49e95 38 *
phungductung 0:e87aa4c49e95 39 * @code
phungductung 0:e87aa4c49e95 40 * error("That shouldn't have happened!");
phungductung 0:e87aa4c49e95 41 * @endcode
phungductung 0:e87aa4c49e95 42 *
phungductung 0:e87aa4c49e95 43 * If the mbed running the program executes this function, it will print the
phungductung 0:e87aa4c49e95 44 * message via the USB serial port, and then die with the blue lights of death!
phungductung 0:e87aa4c49e95 45 *
phungductung 0:e87aa4c49e95 46 * The message can use printf-style formatting, so you can report variables in the
phungductung 0:e87aa4c49e95 47 * message too. For example, you could use this to check a run-time condition:
phungductung 0:e87aa4c49e95 48 *
phungductung 0:e87aa4c49e95 49 * @code
phungductung 0:e87aa4c49e95 50 * if(x >= 5) {
phungductung 0:e87aa4c49e95 51 * error("expected x to be less than 5, but got %d", x);
phungductung 0:e87aa4c49e95 52 * }
phungductung 0:e87aa4c49e95 53 * #endcode
phungductung 0:e87aa4c49e95 54 */
