esokic 0:05aad811ea07 19 /** To generate a fatal compile-time error, you can use the pre-processor #error directive.
esokic 0:05aad811ea07 20 *
esokic 0:05aad811ea07 21 * @code
esokic 0:05aad811ea07 22 * #error "That shouldn't have happened!"
esokic 0:05aad811ea07 23 * @endcode
esokic 0:05aad811ea07 24 *
esokic 0:05aad811ea07 25 * If the compiler evaluates this line, it will report the error and stop the compile.
esokic 0:05aad811ea07 26 *
esokic 0:05aad811ea07 27 * For example, you could use this to check some user-defined compile-time variables:
esokic 0:05aad811ea07 28 *
esokic 0:05aad811ea07 29 * @code
esokic 0:05aad811ea07 30 * #define NUM_PORTS 7
esokic 0:05aad811ea07 31 * #if (NUM_PORTS > 4)
esokic 0:05aad811ea07 32 * #error "NUM_PORTS must be less than 4"
esokic 0:05aad811ea07 33 * #endif
esokic 0:05aad811ea07 34 * @endcode
esokic 0:05aad811ea07 35 *
esokic 0:05aad811ea07 36 * Reporting Run-Time Errors:
esokic 0:05aad811ea07 37 * To generate a fatal run-time error, you can use the mbed error() function.
esokic 0:05aad811ea07 38 *
esokic 0:05aad811ea07 39 * @code
esokic 0:05aad811ea07 40 * error("That shouldn't have happened!");
esokic 0:05aad811ea07 41 * @endcode
esokic 0:05aad811ea07 42 *
esokic 0:05aad811ea07 43 * If the mbed running the program executes this function, it will print the
esokic 0:05aad811ea07 44 * message via the USB serial port, and then die with the blue lights of death!
esokic 0:05aad811ea07 45 *
esokic 0:05aad811ea07 46 * The message can use printf-style formatting, so you can report variables in the
esokic 0:05aad811ea07 47 * message too. For example, you could use this to check a run-time condition:
esokic 0:05aad811ea07 48 *
esokic 0:05aad811ea07 49 * @code
esokic 0:05aad811ea07 50 * if(x >= 5) {
esokic 0:05aad811ea07 51 * error("expected x to be less than 5, but got %d", x);
esokic 0:05aad811ea07 52 * }
esokic 0:05aad811ea07 53 * #endcode
