mbed_official 0:fd0d7bdfcdc2 25 /** To generate a fatal compile-time error, you can use the pre-processor #error directive.
mbed_official 0:fd0d7bdfcdc2 26 *
mbed_official 0:fd0d7bdfcdc2 27 * @code
mbed_official 0:fd0d7bdfcdc2 28 * #error "That shouldn't have happened!"

mbed_official 0:fd0d7bdfcdc2 31 * If the compiler evaluates this line, it will report the error and stop the compile.
mbed_official 0:fd0d7bdfcdc2 32 *
mbed_official 0:fd0d7bdfcdc2 33 * For example, you could use this to check some user-defined compile-time variables:
mbed_official 0:fd0d7bdfcdc2 34 *
mbed_official 0:fd0d7bdfcdc2 35 * @code
mbed_official 0:fd0d7bdfcdc2 36 * #define NUM_PORTS 7
mbed_official 0:fd0d7bdfcdc2 37 * #if (NUM_PORTS > 4)
mbed_official 0:fd0d7bdfcdc2 38 * #error "NUM_PORTS must be less than 4"
mbed_official 0:fd0d7bdfcdc2 39 * #endif
mbed_official 0:fd0d7bdfcdc2 40 * @endcode
mbed_official 0:fd0d7bdfcdc2 41 *
mbed_official 0:fd0d7bdfcdc2 42 * Reporting Run-Time Errors:
mbed_official 0:fd0d7bdfcdc2 43 * To generate a fatal run-time error, you can use the mbed error() function.
mbed_official 0:fd0d7bdfcdc2 44 *
mbed_official 0:fd0d7bdfcdc2 45 * @code
mbed_official 0:fd0d7bdfcdc2 46 * error("That shouldn't have happened!");
mbed_official 0:fd0d7bdfcdc2 47 * @endcode
mbed_official 0:fd0d7bdfcdc2 48 *
mbed_official 0:fd0d7bdfcdc2 49 * If the mbed running the program executes this function, it will print the
mbed_official 0:fd0d7bdfcdc2 50 * message via the USB serial port, and then die with the blue lights of death!
mbed_official 0:fd0d7bdfcdc2 51 *
mbed_official 0:fd0d7bdfcdc2 52 * The message can use printf-style formatting, so you can report variables in the
mbed_official 0:fd0d7bdfcdc2 53 * message too. For example, you could use this to check a run-time condition:
mbed_official 0:fd0d7bdfcdc2 54 *
mbed_official 0:fd0d7bdfcdc2 55 * @code
mbed_official 0:fd0d7bdfcdc2 56 * if(x >= 5) {
mbed_official 0:fd0d7bdfcdc2 57 * error("expected x to be less than 5, but got %d", x);
mbed_official 0:fd0d7bdfcdc2 58 * }
mbed_official 0:fd0d7bdfcdc2 59 * #endcode
