示例1: tryOneFunction

// Any results?
if typ.NumOut() == 0 {
return // Nothing to do.
}
// Right number of arguments + results?
if typ.NumIn()+typ.NumOut() != len(args) {
return
}
// Right argument and result types?
for i, a := range args {
if i < typ.NumIn() {
if !compatible(a, typ.In(i)) {
return
}

}
}
// Build the call args.
argsVal := make([]reflect.Value, typ.NumIn()+typ.NumOut())
for i, a := range args {

}
// Call the function and see if the results are as expected.
