elessair 0:f269e3021894 23 *
elessair 0:f269e3021894 24 * @code
elessair 0:f269e3021894 25 * #error "That shouldn't have happened!"

elessair 0:f269e3021894 28 * If the compiler evaluates this line, it will report the error and stop the compile.
elessair 0:f269e3021894 29 *
elessair 0:f269e3021894 30 * For example, you could use this to check some user-defined compile-time variables:
elessair 0:f269e3021894 31 *
elessair 0:f269e3021894 32 * @code
elessair 0:f269e3021894 33 * #define NUM_PORTS 7
elessair 0:f269e3021894 34 * #if (NUM_PORTS > 4)
elessair 0:f269e3021894 35 * #error "NUM_PORTS must be less than 4"
elessair 0:f269e3021894 36 * #endif
elessair 0:f269e3021894 37 * @endcode
elessair 0:f269e3021894 38 *
elessair 0:f269e3021894 39 * Reporting Run-Time Errors:
elessair 0:f269e3021894 40 * To generate a fatal run-time error, you can use the mbed error() function.
elessair 0:f269e3021894 41 *
elessair 0:f269e3021894 42 * @code
elessair 0:f269e3021894 43 * error("That shouldn't have happened!");
elessair 0:f269e3021894 44 * @endcode
elessair 0:f269e3021894 45 *
elessair 0:f269e3021894 46 * If the mbed running the program executes this function, it will print the
elessair 0:f269e3021894 47 * message via the USB serial port, and then die with the blue lights of death!
elessair 0:f269e3021894 48 *
elessair 0:f269e3021894 49 * The message can use printf-style formatting, so you can report variables in the
elessair 0:f269e3021894 50 * message too. For example, you could use this to check a run-time condition:
elessair 0:f269e3021894 51 *
elessair 0:f269e3021894 52 * @code
elessair 0:f269e3021894 53 * if(x >= 5) {
elessair 0:f269e3021894 54 * error("expected x to be less than 5, but got %d", x);
elessair 0:f269e3021894 55 * }
elessair 0:f269e3021894 56 * #endcode
