bogdanm 13:0645d8841f51 21 * @code
bogdanm 13:0645d8841f51 22 * #error "That shouldn't have happened!"

bogdanm 13:0645d8841f51 25 * If the compiler evaluates this line, it will report the error and stop the compile.
bogdanm 13:0645d8841f51 26 *
bogdanm 13:0645d8841f51 27 * For example, you could use this to check some user-defined compile-time variables:
bogdanm 13:0645d8841f51 28 *
bogdanm 13:0645d8841f51 29 * @code
bogdanm 13:0645d8841f51 30 * #define NUM_PORTS 7
bogdanm 13:0645d8841f51 31 * #if (NUM_PORTS > 4)
bogdanm 13:0645d8841f51 32 * #error "NUM_PORTS must be less than 4"
bogdanm 13:0645d8841f51 33 * #endif
bogdanm 13:0645d8841f51 34 * @endcode
bogdanm 13:0645d8841f51 35 *
bogdanm 13:0645d8841f51 36 * Reporting Run-Time Errors:
bogdanm 13:0645d8841f51 37 * To generate a fatal run-time error, you can use the mbed error() function.
bogdanm 13:0645d8841f51 38 *
bogdanm 13:0645d8841f51 39 * @code
bogdanm 13:0645d8841f51 40 * error("That shouldn't have happened!");
bogdanm 13:0645d8841f51 41 * @endcode
bogdanm 13:0645d8841f51 42 *
bogdanm 13:0645d8841f51 43 * If the mbed running the program executes this function, it will print the
bogdanm 13:0645d8841f51 44 * message via the USB serial port, and then die with the blue lights of death!
bogdanm 13:0645d8841f51 45 *
bogdanm 13:0645d8841f51 46 * The message can use printf-style formatting, so you can report variables in the
bogdanm 13:0645d8841f51 47 * message too. For example, you could use this to check a run-time condition:
bogdanm 13:0645d8841f51 48 *
bogdanm 13:0645d8841f51 49 * @code
bogdanm 13:0645d8841f51 50 * if(x >= 5) {
bogdanm 13:0645d8841f51 51 * error("expected x to be less than 5, but got %d", x);
bogdanm 13:0645d8841f51 52 * }
bogdanm 13:0645d8841f51 53 * #endcode
