This projects make an easy C++11 access to a shared memory. The Shared Memeory is part of the Linux kernal system and the used device could be found under /dev/shm. This example shows how to use the project:
#include <iostream>
#include <string>
using namespace std;
#include <libshm/libshm.hpp>
using namespace shm;
int main(int argc, char **argv){
if(argc == 2){
if(std::string(argv[1]) == "server"){
int val = 50;
Shm<0x1234, int>::create();
Shm<0x1234, int> shm;
shm.setElement(&val);
}else
if(std::string(argv[1]) == "client"){
Shm<0x1234, int> shm;
const int* ptr = shm.getElement();
std::cout <<"Val = " << *ptr <<std::endl;
Shm<0x1234, int>::destroy();
}
}else{
std::cerr<<"Usage shm [server][client]"<<std::endl;
}
return 0;
}#install libshm
this project is build using WAF. To Compile ind install the project use the waf progamm included in the project. The standard installation directory ist /usr/local/include.
