Exception and Error Handling

This section shows the error mechanisms implemented by the C++ and
the TCL interfaces.

Error Mechanisms for the C++ Interface

The following code block shows an example of how to use the exception
handling with the API.

try

{

IGCGenerator myGenerator;

myGenerator.Connect(0);

myGenerator.Foo();

}

catch (IGCError err)

{

// Error occurred in try block

// Do error handling here, e.g. print error message:

cerr << "Error occurred: " << err;

}

To throw an error, use a line similar to the one below:

throw(IGCError(IGCError::IGE_FATAL, "Cannot close device"));
