mbed_official 0:fd0d7bdfcdc2 19 /** To generate a fatal compile-time error, you can use the pre-processor #error directive.
mbed_official 0:fd0d7bdfcdc2 20 *
mbed_official 0:fd0d7bdfcdc2 21 * @code
mbed_official 0:fd0d7bdfcdc2 22 * #error "That shouldn't have happened!"

mbed_official 0:fd0d7bdfcdc2 25 * If the compiler evaluates this line, it will report the error and stop the compile.
mbed_official 0:fd0d7bdfcdc2 26 *
mbed_official 0:fd0d7bdfcdc2 27 * For example, you could use this to check some user-defined compile-time variables:
mbed_official 0:fd0d7bdfcdc2 28 *
mbed_official 0:fd0d7bdfcdc2 29 * @code
mbed_official 0:fd0d7bdfcdc2 30 * #define NUM_PORTS 7
mbed_official 0:fd0d7bdfcdc2 31 * #if (NUM_PORTS > 4)
mbed_official 0:fd0d7bdfcdc2 32 * #error "NUM_PORTS must be less than 4"
mbed_official 0:fd0d7bdfcdc2 33 * #endif
mbed_official 0:fd0d7bdfcdc2 34 * @endcode
mbed_official 0:fd0d7bdfcdc2 35 *
mbed_official 0:fd0d7bdfcdc2 36 * Reporting Run-Time Errors:
mbed_official 0:fd0d7bdfcdc2 37 * To generate a fatal run-time error, you can use the mbed error() function.
mbed_official 0:fd0d7bdfcdc2 38 *
mbed_official 0:fd0d7bdfcdc2 39 * @code
mbed_official 0:fd0d7bdfcdc2 40 * error("That shouldn't have happened!");
mbed_official 0:fd0d7bdfcdc2 41 * @endcode
mbed_official 0:fd0d7bdfcdc2 42 *
emilmont 2:143cac498751 43 * If the mbed running the program executes this function, it will print the
mbed_official 0:fd0d7bdfcdc2 44 * message via the USB serial port, and then die with the blue lights of death!
mbed_official 0:fd0d7bdfcdc2 45 *
emilmont 2:143cac498751 46 * The message can use printf-style formatting, so you can report variables in the
mbed_official 0:fd0d7bdfcdc2 47 * message too. For example, you could use this to check a run-time condition:
emilmont 2:143cac498751 48 *
mbed_official 0:fd0d7bdfcdc2 49 * @code
mbed_official 0:fd0d7bdfcdc2 50 * if(x >= 5) {
mbed_official 0:fd0d7bdfcdc2 51 * error("expected x to be less than 5, but got %d", x);
mbed_official 0:fd0d7bdfcdc2 52 * }
mbed_official 0:fd0d7bdfcdc2 53 * #endcode
