bogdanm 65:5798e58a58b1 19 /** To generate a fatal compile-time error, you can use the pre-processor #error directive.
bogdanm 65:5798e58a58b1 20 *
bogdanm 65:5798e58a58b1 21 * @code
bogdanm 65:5798e58a58b1 22 * #error "That shouldn't have happened!"
bogdanm 65:5798e58a58b1 23 * @endcode
bogdanm 65:5798e58a58b1 24 *
bogdanm 65:5798e58a58b1 25 * If the compiler evaluates this line, it will report the error and stop the compile.
bogdanm 65:5798e58a58b1 26 *
bogdanm 65:5798e58a58b1 27 * For example, you could use this to check some user-defined compile-time variables:
bogdanm 65:5798e58a58b1 28 *
bogdanm 65:5798e58a58b1 29 * @code
bogdanm 65:5798e58a58b1 30 * #define NUM_PORTS 7
bogdanm 65:5798e58a58b1 31 * #if (NUM_PORTS > 4)
bogdanm 65:5798e58a58b1 32 * #error "NUM_PORTS must be less than 4"
bogdanm 65:5798e58a58b1 33 * #endif
bogdanm 65:5798e58a58b1 34 * @endcode
bogdanm 65:5798e58a58b1 35 *
bogdanm 65:5798e58a58b1 36 * Reporting Run-Time Errors:
bogdanm 65:5798e58a58b1 37 * To generate a fatal run-time error, you can use the mbed error() function.
bogdanm 65:5798e58a58b1 38 *
bogdanm 65:5798e58a58b1 39 * @code
bogdanm 65:5798e58a58b1 40 * error("That shouldn't have happened!");
bogdanm 65:5798e58a58b1 41 * @endcode
bogdanm 65:5798e58a58b1 42 *
bogdanm 65:5798e58a58b1 43 * If the mbed running the program executes this function, it will print the
bogdanm 65:5798e58a58b1 44 * message via the USB serial port, and then die with the blue lights of death!
bogdanm 65:5798e58a58b1 45 *
bogdanm 65:5798e58a58b1 46 * The message can use printf-style formatting, so you can report variables in the
bogdanm 65:5798e58a58b1 47 * message too. For example, you could use this to check a run-time condition:
bogdanm 65:5798e58a58b1 48 *
bogdanm 65:5798e58a58b1 49 * @code
bogdanm 65:5798e58a58b1 50 * if(x >= 5) {
bogdanm 65:5798e58a58b1 51 * error("expected x to be less than 5, but got %d", x);
bogdanm 65:5798e58a58b1 52 * }
bogdanm 65:5798e58a58b1 53 * #endcode
