gkroussos 0:dd0fea342ad2 19 /** To generate a fatal compile-time error, you can use the pre-processor #error directive.
gkroussos 0:dd0fea342ad2 20 *
gkroussos 0:dd0fea342ad2 21 * @code
gkroussos 0:dd0fea342ad2 22 * #error "That shouldn't have happened!"

gkroussos 0:dd0fea342ad2 25 * If the compiler evaluates this line, it will report the error and stop the compile.
gkroussos 0:dd0fea342ad2 26 *
gkroussos 0:dd0fea342ad2 27 * For example, you could use this to check some user-defined compile-time variables:
gkroussos 0:dd0fea342ad2 28 *
gkroussos 0:dd0fea342ad2 29 * @code
gkroussos 0:dd0fea342ad2 30 * #define NUM_PORTS 7
gkroussos 0:dd0fea342ad2 31 * #if (NUM_PORTS > 4)
gkroussos 0:dd0fea342ad2 32 * #error "NUM_PORTS must be less than 4"
gkroussos 0:dd0fea342ad2 33 * #endif
gkroussos 0:dd0fea342ad2 34 * @endcode
gkroussos 0:dd0fea342ad2 35 *
gkroussos 0:dd0fea342ad2 36 * Reporting Run-Time Errors:
gkroussos 0:dd0fea342ad2 37 * To generate a fatal run-time error, you can use the mbed error() function.
gkroussos 0:dd0fea342ad2 38 *
gkroussos 0:dd0fea342ad2 39 * @code
gkroussos 0:dd0fea342ad2 40 * error("That shouldn't have happened!");
gkroussos 0:dd0fea342ad2 41 * @endcode
gkroussos 0:dd0fea342ad2 42 *
gkroussos 0:dd0fea342ad2 43 * If the mbed running the program executes this function, it will print the
gkroussos 0:dd0fea342ad2 44 * message via the USB serial port, and then die with the blue lights of death!
gkroussos 0:dd0fea342ad2 45 *
gkroussos 0:dd0fea342ad2 46 * The message can use printf-style formatting, so you can report variables in the
gkroussos 0:dd0fea342ad2 47 * message too. For example, you could use this to check a run-time condition:
gkroussos 0:dd0fea342ad2 48 *
gkroussos 0:dd0fea342ad2 49 * @code
gkroussos 0:dd0fea342ad2 50 * if(x >= 5) {
gkroussos 0:dd0fea342ad2 51 * error("expected x to be less than 5, but got %d", x);
gkroussos 0:dd0fea342ad2 52 * }
gkroussos 0:dd0fea342ad2 53 * #endcode
