slowness 0:c03cffe402df 9 * To generate a fatal compile-time error, you can use the pre-processor #error directive.
slowness 0:c03cffe402df 10 *
slowness 0:c03cffe402df 11 * > #error "That shouldn't have happened!"
slowness 0:c03cffe402df 12 *
slowness 0:c03cffe402df 13 * If the compiler evaluates this line, it will report the error and stop the compile.
slowness 0:c03cffe402df 14 *
slowness 0:c03cffe402df 15 * For example, you could use this to check some user-defined compile-time variables:
slowness 0:c03cffe402df 16 *
slowness 0:c03cffe402df 17 * > #define NUM_PORTS 7
slowness 0:c03cffe402df 18 * > #if (NUM_PORTS > 4)
slowness 0:c03cffe402df 19 * > #error "NUM_PORTS must be less than 4"
slowness 0:c03cffe402df 20 * > #endif
slowness 0:c03cffe402df 21 *
slowness 0:c03cffe402df 22 * Reporting Run-Time Errors:
slowness 0:c03cffe402df 23 * To generate a fatal run-time error, you can use the mbed error() function.
slowness 0:c03cffe402df 24 *
slowness 0:c03cffe402df 25 * > error("That shouldn't have happened!");
slowness 0:c03cffe402df 26 *
slowness 0:c03cffe402df 27 * If the mbed running the program executes this function, it will print the
slowness 0:c03cffe402df 28 * message via the USB serial port, and then die with the blue lights of death!
slowness 0:c03cffe402df 29 *
slowness 0:c03cffe402df 30 * The message can use printf-style formatting, so you can report variables in the
slowness 0:c03cffe402df 31 * message too. For example, you could use this to check a run-time condition:
slowness 0:c03cffe402df 32 *
slowness 0:c03cffe402df 33 * > if(x >= 5) {
slowness 0:c03cffe402df 34 * > error("expected x to be less than 5, but got %d", x);
slowness 0:c03cffe402df 35 * > }
