hayama 0:da22b0b4395a 19 /** To generate a fatal compile-time error, you can use the pre-processor #error directive.
hayama 0:da22b0b4395a 20 *
hayama 0:da22b0b4395a 21 * @code
hayama 0:da22b0b4395a 22 * #error "That shouldn't have happened!"

hayama 0:da22b0b4395a 25 * If the compiler evaluates this line, it will report the error and stop the compile.
hayama 0:da22b0b4395a 26 *
hayama 0:da22b0b4395a 27 * For example, you could use this to check some user-defined compile-time variables:
hayama 0:da22b0b4395a 28 *
hayama 0:da22b0b4395a 29 * @code
hayama 0:da22b0b4395a 30 * #define NUM_PORTS 7
hayama 0:da22b0b4395a 31 * #if (NUM_PORTS > 4)
hayama 0:da22b0b4395a 32 * #error "NUM_PORTS must be less than 4"
hayama 0:da22b0b4395a 33 * #endif
hayama 0:da22b0b4395a 34 * @endcode
hayama 0:da22b0b4395a 35 *
hayama 0:da22b0b4395a 36 * Reporting Run-Time Errors:
hayama 0:da22b0b4395a 37 * To generate a fatal run-time error, you can use the mbed error() function.
hayama 0:da22b0b4395a 38 *
hayama 0:da22b0b4395a 39 * @code
hayama 0:da22b0b4395a 40 * error("That shouldn't have happened!");
hayama 0:da22b0b4395a 41 * @endcode
hayama 0:da22b0b4395a 42 *
hayama 0:da22b0b4395a 43 * If the mbed running the program executes this function, it will print the
hayama 0:da22b0b4395a 44 * message via the USB serial port, and then die with the blue lights of death!
hayama 0:da22b0b4395a 45 *
hayama 0:da22b0b4395a 46 * The message can use printf-style formatting, so you can report variables in the
hayama 0:da22b0b4395a 47 * message too. For example, you could use this to check a run-time condition:
hayama 0:da22b0b4395a 48 *
hayama 0:da22b0b4395a 49 * @code
hayama 0:da22b0b4395a 50 * if(x >= 5) {
hayama 0:da22b0b4395a 51 * error("expected x to be less than 5, but got %d", x);
hayama 0:da22b0b4395a 52 * }
hayama 0:da22b0b4395a 53 * #endcode
