borlanic 0:380207fcb5c1 34 * #error "That shouldn't have happened!"

borlanic 0:380207fcb5c1 37 * If the compiler evaluates this line, it will report the error and stop the compile.
borlanic 0:380207fcb5c1 38 *
borlanic 0:380207fcb5c1 39 * For example, you could use this to check some user-defined compile-time variables:
borlanic 0:380207fcb5c1 40 *
borlanic 0:380207fcb5c1 41 * @code
borlanic 0:380207fcb5c1 42 * #define NUM_PORTS 7
borlanic 0:380207fcb5c1 43 * #if (NUM_PORTS > 4)
borlanic 0:380207fcb5c1 44 * #error "NUM_PORTS must be less than 4"
borlanic 0:380207fcb5c1 45 * #endif
borlanic 0:380207fcb5c1 46 * @endcode
borlanic 0:380207fcb5c1 47 *
borlanic 0:380207fcb5c1 48 * Reporting Run-Time Errors:
borlanic 0:380207fcb5c1 49 * To generate a fatal run-time error, you can use the mbed error() function.
borlanic 0:380207fcb5c1 50 *
borlanic 0:380207fcb5c1 51 * @code
borlanic 0:380207fcb5c1 52 * error("That shouldn't have happened!");
borlanic 0:380207fcb5c1 53 * @endcode
borlanic 0:380207fcb5c1 54 *
borlanic 0:380207fcb5c1 55 * If the mbed running the program executes this function, it will print the
borlanic 0:380207fcb5c1 56 * message via the USB serial port, and then die with the blue lights of death!
borlanic 0:380207fcb5c1 57 *
borlanic 0:380207fcb5c1 58 * The message can use printf-style formatting, so you can report variables in the
borlanic 0:380207fcb5c1 59 * message too. For example, you could use this to check a run-time condition:
borlanic 0:380207fcb5c1 60 *
borlanic 0:380207fcb5c1 61 * @code
borlanic 0:380207fcb5c1 62 * if(x >= 5) {
borlanic 0:380207fcb5c1 63 * error("expected x to be less than 5, but got %d", x);
borlanic 0:380207fcb5c1 64 * }
borlanic 0:380207fcb5c1 65 * @endcode
borlanic 0:380207fcb5c1 66 *
borlanic 0:380207fcb5c1 67 *
