64-bit

问题 Below is an extract of some code I am using to simulate key presses via the SendInput API. This works correctly if I set my application to compile for an x86 CPU, but doesn't work for x64 CPU compilation. I'm guessing it has something todo with the fact that x64 uses double size pointers, but I tried to change this [FieldOffset(4)] to this [FieldOffset(8)] but it didn't work. Could it be something to do with the fact it is importing the 32bit version of user32.dll? #region SendInput API

问题 How do I use RIP Relative Addressing in a Linux assembly program for the AMD64 archtitecture? I am looking for a simple example (a Hello world program) that uses the AMD64 RIP relative adressing mode. For example the following 64-bit assembly program would work with normal (absolute addressing): .text .global _start _start: mov $0xd, %rdx mov $msg, %rsi pushq $0x1 pop %rax mov %rax, %rdi syscall xor %rdi, %rdi pushq $0x3c pop %rax syscall .data msg: .ascii "Hello world!\n" I am guessing that

问题 I am trying to adapt an existing code to a 64 bit machine. The main problem is that in one function, the previous coder uses a void* argument that is converted into suitable type in the function itself. A short example: void function(MESSAGE_ID id, void* param) { if(id == FOO) { int real_param = (int)param; // ... } } Of course, on a 64 bit machine, I get the error: error: cast from 'void*' to 'int' loses precision I would like to correct this so that it still works on a 32 bit machine and as

问题 We have a 32-bit C++ GUI application running on 32 bit windows 7. We are planning to migrate our server with C++ apps to 64-bit linux. We have noticed that long types are larger in 64 bit. This will be incompatible with the client-server message passing from 64-bit to 32-bit. What is a good way to solve this incompatibility? Do we need to change the code? How? or Do we use a third party software to do the conversion? What software is it? 回答1: That's why there is the standardized int32_t and

问题 I have a x64 application. It is a bit heavy application (in terms of thread counts, memory needed etc). I'm running this application on a 4GB RAM 64-bit Windows7 Quad core machine. But what i notice is after my application takes around 2.2-2.3 GB Ram it crashes. Is this required behavious? Can 64bit applications at max take only 2.3-2.4 GB RAM from 4GB RAM? 回答1: No, check that you don't have any overflows or other bugs first. Even 32-bit applications can address - use more RAM, so it would be
