ClementBreteau 1:f3f702086a30 9 * To generate a fatal compile-time error, you can use the pre-processor #error directive.
ClementBreteau 1:f3f702086a30 10 *
ClementBreteau 1:f3f702086a30 11 * > #error "That shouldn't have happened!"
ClementBreteau 1:f3f702086a30 12 *
ClementBreteau 1:f3f702086a30 13 * If the compiler evaluates this line, it will report the error and stop the compile.
ClementBreteau 1:f3f702086a30 14 *
ClementBreteau 1:f3f702086a30 15 * For example, you could use this to check some user-defined compile-time variables:
ClementBreteau 1:f3f702086a30 16 *
ClementBreteau 1:f3f702086a30 17 * > #define NUM_PORTS 7
ClementBreteau 1:f3f702086a30 18 * > #if (NUM_PORTS > 4)
ClementBreteau 1:f3f702086a30 19 * > #error "NUM_PORTS must be less than 4"
ClementBreteau 1:f3f702086a30 20 * > #endif
ClementBreteau 1:f3f702086a30 21 *
ClementBreteau 1:f3f702086a30 22 * Reporting Run-Time Errors:
ClementBreteau 1:f3f702086a30 23 * To generate a fatal run-time error, you can use the mbed error() function.
ClementBreteau 1:f3f702086a30 24 *
ClementBreteau 1:f3f702086a30 25 * > error("That shouldn't have happened!");
ClementBreteau 1:f3f702086a30 26 *
ClementBreteau 1:f3f702086a30 27 * If the mbed running the program executes this function, it will print the
ClementBreteau 1:f3f702086a30 28 * message via the USB serial port, and then die with the blue lights of death!
ClementBreteau 1:f3f702086a30 29 *
ClementBreteau 1:f3f702086a30 30 * The message can use printf-style formatting, so you can report variables in the
ClementBreteau 1:f3f702086a30 31 * message too. For example, you could use this to check a run-time condition:
ClementBreteau 1:f3f702086a30 32 *
ClementBreteau 1:f3f702086a30 33 * > if(x >= 5) {
ClementBreteau 1:f3f702086a30 34 * > error("expected x to be less than 5, but got %d", x);
ClementBreteau 1:f3f702086a30 35 * > }
