/** To generate a fatal compile-time error, you can use the pre-processor #error directive.
|
|
*
|
|
* @code
|
|
* #error "That shouldn't have happened!"
|
|
* @endcode
|
|
*
|
|
* If the compiler evaluates this line, it will report the error and stop the compile.
|
|
*
|
|
* For example, you could use this to check some user-defined compile-time variables:
|
|
*
|
|
* @code
|
|
* #define NUM_PORTS 7
|
|
* #if (NUM_PORTS > 4)
|
|
* #error "NUM_PORTS must be less than 4"
|
|
* #endif
|
|
* @endcode
|
|
*
|
|
* Reporting Run-Time Errors:
|
|
* To generate a fatal run-time error, you can use the mbed error() function.
|
|
*
|
|
* @code
|
|
* error("That shouldn't have happened!");
|
|
* @endcode
|
|
*
|
|
* If the mbed running the program executes this function, it will print the
|
|
* message via the USB serial port, and then die with the blue lights of death!
|
|
*
|
|
* The message can use printf-style formatting, so you can report variables in the
|
|
* message too. For example, you could use this to check a run-time condition:
|
|
*
|
|
* @code
|
|
* if(x >= 5) {
|
|
* error("expected x to be less than 5, but got %d", x);
|
|
* }
|
|
* #endcode
|
