shared

问题 I'm get kind of getting mixed messages about this so I'm hoping someone can clear this up for me. Should I be using Shared methods/functions in the following situation: I have a generic class named "Person". This class represents a person in the database. I have a manager class named "PersonManager". This class contains methods which adds, updates, deletes individual Person objects. A method also exists to lookup Persons from the database. Should these methods in the manager class be declared

问题 The Windows API offers the CreateFileMappingNuma function (http://msdn.microsoft.com/en-us/library/windows/desktop/aa366539(v=vs.85).aspx) to create a named shared memory space on a specific NUMA node. So far, I have not found an equivalent function for Linux. My current approach looks like this: Allocate named shared memory (using shm_open(...)) Determine current NUMA node (using numa_move_pages(...)) Move pages to target Node (using numa_move_pages(...) again) Does anyone know a better

问题 I have a library ( libfoo ) that is compiled using libtool into two objects: libfoo.a and libfoo.so. I have to create, using libtool also, another library ( libbar ) that will be a single shared library (libbar.so) containing all libfoo's code. In order to do this, I have to force libbar to link against libfoo.a , and not libfoo.so. I am in an autotools environment, so I have to solve this using standard configure.in or Makefile.am rules. I tried several things, like in configure.in : LDFLAGS

问题 I am working with std::shared_ptr and during my software development I met a couple of cases that let me doubt about memory management. I had a third party library that gave me always raw pointers from functions and in my code I was transforming them into std::shared_ptr (from std and not from boost. By the way what is the difference between the two?). So let's say I have the following code: ClassA* raw = new ClassA; std::shared_ptr<ClassA> shared(raw); What happens now when the shared

问题 My application dynamically loads liba.so (with dlopen ). liba.so uses libb.so so I want to link liba.so against libb.so . How to do this in Linux? Thanks in advance. 回答1: If you build liba.so yourself, you need to link it with -l option gcc -o liba.so liba.o -L/libb/path -lb If you don't have liba sources, perhaps you could create libawrapper.so linked against liba and libb and to load dynamically this library gcc -o libawrap.so -L/liba/ -L/libb/ -la -lb 来源： https://stackoverflow.com

问题 I am trying to juggle objects using std::shared_ptr and std::weak_ptr . The scenario is something like this: I have objects of class channel which is derived from a abstract class abstract::channel (with pure virtual functions). I have a container channelContainer ( std::vector ) containing shared pointers ( std::shared_ptr ) to channel Objects. Now, I have a deque (std::deque) containing weak pointers (std::weak_ptr) to each of the object in the channelContainer . Lets name this deque

问题 I'm looking for a program to view and browse the (local) shared memory in Windows x32/x64. I know this exists because I've seen it in action before. For some reason Google and MSDN fail me on this one. 回答1: I think Accesschk can do this. From the commandline: accesschk.exe -osv > objects.txt Search for: "Type: Section" 来源： https://stackoverflow.com/questions/465378/program-to-view-shared-memory-in-windows
