SquirrelGod 2:99b1cb0d9f5e 8 /* Reporting Compile-Time Errors:
SquirrelGod 2:99b1cb0d9f5e 9 * To generate a fatal compile-time error, you can use the pre-processor #error directive.
SquirrelGod 2:99b1cb0d9f5e 10 *
SquirrelGod 2:99b1cb0d9f5e 11 * > #error "That shouldn't have happened!"
SquirrelGod 2:99b1cb0d9f5e 12 *
SquirrelGod 2:99b1cb0d9f5e 13 * If the compiler evaluates this line, it will report the error and stop the compile.
SquirrelGod 2:99b1cb0d9f5e 14 *
SquirrelGod 2:99b1cb0d9f5e 15 * For example, you could use this to check some user-defined compile-time variables:
SquirrelGod 2:99b1cb0d9f5e 16 *
SquirrelGod 2:99b1cb0d9f5e 17 * > #define NUM_PORTS 7
SquirrelGod 2:99b1cb0d9f5e 18 * > #if (NUM_PORTS > 4)
SquirrelGod 2:99b1cb0d9f5e 19 * > #error "NUM_PORTS must be less than 4"
SquirrelGod 2:99b1cb0d9f5e 20 * > #endif
SquirrelGod 2:99b1cb0d9f5e 21 *
SquirrelGod 2:99b1cb0d9f5e 22 * Reporting Run-Time Errors:
SquirrelGod 2:99b1cb0d9f5e 23 * To generate a fatal run-time error, you can use the mbed error() function.
SquirrelGod 2:99b1cb0d9f5e 24 *
SquirrelGod 2:99b1cb0d9f5e 25 * > error("That shouldn't have happened!");
SquirrelGod 2:99b1cb0d9f5e 26 *
SquirrelGod 2:99b1cb0d9f5e 27 * If the mbed running the program executes this function, it will print the
SquirrelGod 2:99b1cb0d9f5e 28 * message via the USB serial port, and then die with the blue lights of death!
SquirrelGod 2:99b1cb0d9f5e 29 *
SquirrelGod 2:99b1cb0d9f5e 30 * The message can use printf-style formatting, so you can report variables in the
SquirrelGod 2:99b1cb0d9f5e 31 * message too. For example, you could use this to check a run-time condition:
SquirrelGod 2:99b1cb0d9f5e 32 *
SquirrelGod 2:99b1cb0d9f5e 33 * > if(x >= 5) {
SquirrelGod 2:99b1cb0d9f5e 34 * > error("expected x to be less than 5, but got %d", x);
SquirrelGod 2:99b1cb0d9f5e 35 * > }
