KISScientific 0:d75ca4e39672 9 /* Reporting Compile-Time Errors:
KISScientific 0:d75ca4e39672 10 * To generate a fatal compile-time error, you can use the pre-processor #error directive.
KISScientific 0:d75ca4e39672 11 *
KISScientific 0:d75ca4e39672 12 * > #error "That shouldn't have happened!"
KISScientific 0:d75ca4e39672 13 *
KISScientific 0:d75ca4e39672 14 * If the compiler evaluates this line, it will report the error and stop the compile.
KISScientific 0:d75ca4e39672 15 *
KISScientific 0:d75ca4e39672 16 * For example, you could use this to check some user-defined compile-time variables:
KISScientific 0:d75ca4e39672 17 *
KISScientific 0:d75ca4e39672 18 * > #define NUM_PORTS 7
KISScientific 0:d75ca4e39672 19 * > #if (NUM_PORTS > 4)
KISScientific 0:d75ca4e39672 20 * > #error "NUM_PORTS must be less than 4"
KISScientific 0:d75ca4e39672 21 * > #endif
KISScientific 0:d75ca4e39672 22 *
KISScientific 0:d75ca4e39672 23 * Reporting Run-Time Errors:
KISScientific 0:d75ca4e39672 24 * To generate a fatal run-time error, you can use the mbed error() function.
KISScientific 0:d75ca4e39672 25 *
KISScientific 0:d75ca4e39672 26 * > error("That shouldn't have happened!");
KISScientific 0:d75ca4e39672 27 *
KISScientific 0:d75ca4e39672 28 * If the mbed running the program executes this function, it will print the
KISScientific 0:d75ca4e39672 29 * message via the USB serial port, and then die with the blue lights of death!
KISScientific 0:d75ca4e39672 30 *
KISScientific 0:d75ca4e39672 31 * The message can use printf-style formatting, so you can report variables in the
KISScientific 0:d75ca4e39672 32 * message too. For example, you could use this to check a run-time condition:
KISScientific 0:d75ca4e39672 33 *
KISScientific 0:d75ca4e39672 34 * > if(x >= 5) {
KISScientific 0:d75ca4e39672 35 * > error("expected x to be less than 5, but got %d", x);
KISScientific 0:d75ca4e39672 36 * > }
