MikamiUitOpen 2:dcaee06f6ccb 19 /** To generate a fatal compile-time error, you can use the pre-processor #error directive.
MikamiUitOpen 2:dcaee06f6ccb 20 *
MikamiUitOpen 2:dcaee06f6ccb 21 * @code
MikamiUitOpen 2:dcaee06f6ccb 22 * #error "That shouldn't have happened!"

MikamiUitOpen 2:dcaee06f6ccb 25 * If the compiler evaluates this line, it will report the error and stop the compile.
MikamiUitOpen 2:dcaee06f6ccb 26 *
MikamiUitOpen 2:dcaee06f6ccb 27 * For example, you could use this to check some user-defined compile-time variables:
MikamiUitOpen 2:dcaee06f6ccb 28 *
MikamiUitOpen 2:dcaee06f6ccb 29 * @code
MikamiUitOpen 2:dcaee06f6ccb 30 * #define NUM_PORTS 7
MikamiUitOpen 2:dcaee06f6ccb 31 * #if (NUM_PORTS > 4)
MikamiUitOpen 2:dcaee06f6ccb 32 * #error "NUM_PORTS must be less than 4"
MikamiUitOpen 2:dcaee06f6ccb 33 * #endif
MikamiUitOpen 2:dcaee06f6ccb 34 * @endcode
MikamiUitOpen 2:dcaee06f6ccb 35 *
MikamiUitOpen 2:dcaee06f6ccb 36 * Reporting Run-Time Errors:
MikamiUitOpen 2:dcaee06f6ccb 37 * To generate a fatal run-time error, you can use the mbed error() function.
MikamiUitOpen 2:dcaee06f6ccb 38 *
MikamiUitOpen 2:dcaee06f6ccb 39 * @code
MikamiUitOpen 2:dcaee06f6ccb 40 * error("That shouldn't have happened!");
MikamiUitOpen 2:dcaee06f6ccb 41 * @endcode
MikamiUitOpen 2:dcaee06f6ccb 42 *
MikamiUitOpen 2:dcaee06f6ccb 43 * If the mbed running the program executes this function, it will print the
MikamiUitOpen 2:dcaee06f6ccb 44 * message via the USB serial port, and then die with the blue lights of death!
MikamiUitOpen 2:dcaee06f6ccb 45 *
MikamiUitOpen 2:dcaee06f6ccb 46 * The message can use printf-style formatting, so you can report variables in the
MikamiUitOpen 2:dcaee06f6ccb 47 * message too. For example, you could use this to check a run-time condition:
MikamiUitOpen 2:dcaee06f6ccb 48 *
MikamiUitOpen 2:dcaee06f6ccb 49 * @code
MikamiUitOpen 2:dcaee06f6ccb 50 * if(x >= 5) {
MikamiUitOpen 2:dcaee06f6ccb 51 * error("expected x to be less than 5, but got %d", x);
MikamiUitOpen 2:dcaee06f6ccb 52 * }
MikamiUitOpen 2:dcaee06f6ccb 53 * #endcode
