Methods of resource processing in functions

In the process of writing a function, there is an exception that needs to end execution, usually using return to end the function, but before an exception occurs, a number of resource persons requested by the function are not released.

At this point, you can set an execution node at the end of the function, and, where the exception occurs, use the Goto statement to jump to the node to perform resource release and return operations.

void function ()

{

if ()//anomaly judgment

{

Goto Erro;

}

Erro:

Release ();

Return

}
