Provides a code snippet to explain how to use User::Leave().
You can use the User::Leave() function to terminate a
function’s processing immediately when an exception condition occurs. In the
example below, if the new fails, the function calls User::Leave() with
an error code. The return type of the function is void, because
it is not necessary to use it to return error information.
void doExampleL()
{
CExample* myExample = new CExample;
if (!myExample) User::Leave(KErrNoMemory);
// leave used in place of return to indicate an error
// do something
myExample->iInt = 5;
testConsole.Printf(_LIT("Value of iInt is %d.\n"),myExample->iInt);
// delete
delete myExample;
}
