memory-address

Go doesn't allow taking the address of a map member: // if I do this: p := &mm["abc"] // Syntax Error - cannot take the address of mm["abc"] The rationale is that if Go allows taking this address, when the map backstore grows or shinks, the address can become invalid, confusing the user. But Go slice gets relocated when it outgrows its capacity, yet, Go allows us to take the address of a slice element: a := make([]Test, 5) a[0] = Test{1, "dsfds"} a[1] = Test{2, "sdfd"} a[2] = Test{3, "dsf"} addr1 := reflect.ValueOf(&a[2]).Pointer() fmt.Println("Address of a[2]: ", addr1) a = append(a, Test{4,

How do I get the absolute address of a member function in C++? (I need this for thunking.) Member function pointers don't work because I can't convert them to absolute addresses ( void * ) -- I need to know the address of the actual function in memory, not simply the address relative to the type. There exists a syntax to get the address of the member function in MSVC (starting from MSVC 2005 IMHO). But it's pretty tricky. Moreover, the obtained pointer is impossible to cast to other pointer type by conventional means. Though there exists a way to do this nevertheless. Here's the example: //

Given knowledge of the prototype of a function and its address in memory, is it possible to call this function from another process or some piece of code that knows nothing but the prototype and memory address? If possible, how can a returned type be handled back in the code? On modern operating systems, each process has its own address space and addresses are only valid within a process. If you want to execute code in some other process, you either have to inject a shared library or attach your program as a debugger . Once you are in the other program's address space, this code invokes a

I know everyone hates gotos. In my code, for reasons I have considered and am comfortable with, they provide an effective solution (ie I'm not looking for "don't do that" as an answer, I understand your reservations, and understand why I am using them anyway). So far they have been fantastic, but I want to expand the functionality in such a way that requires me to essentially be able to store pointers to the labels, then go to them later. If this code worked, it would represent the type of functionality that I need. But it doesn't work, and 30 min of googling hasn't revealed anything. Does
