+
+For instance, to print the pointer `myPointer` declared as `AnyClass*`, you can write:
 ```C++
-CAMITK_TRACE(QString("0x%1").arg((quintptr)myPointer, QT_POINTER_SIZE * 2, 16, QChar('0')))
+CAMITK_INFO(tr("checking ") + CAMITK_PRINT_POINTER(myPointer))
 ```

+This will print:
 ```
-0x00005632e5fd5af0
+checking myPointer=0x00005632e5fd5af0
 ```
 
+For your information, the macro is defined like this:
+```C++
+#define CAMITK_PRINT_POINTER(PTR)    (QString(#PTR) + QString("=0x%1").arg((quintptr)PTR, QT_POINTER_SIZE * 2, 16, QChar('0')))
