Figure 200: Three Casts
Changing a Variable’s Data Type
the data type was changed from int to $char. In the first cast, TotalView
changed the Type for you. In the second, it did not alter the Expression field.
The Expression List Window contains two casting examples. The first casts a
function’s returned value to long long. The second is the same cast as was
made in the two Variable Windows.
TotalView also lets you cast a variable into an array. In the GUI, add an array
specifier to the Type declaration. For example, adding [3] to a variable
declared as an int changes it into an array of three ints.
When TotalView displays some complex arrays and structures, it displays
the compound object or array types in the Variable Window.
Editing a compound object or array data type can produce undesirable results.
TotalView tries to give you what you ask for, so if you get it wrong, the results are unpredictable.
Fortunately, the remedy is quite simple: close the Variable Window and start
over again.
The following sections discuss the following more complex data types.
