Q: What does the header do?
A: This is a template for shared memory.
Q: How many platforms it support?
A: It only support Windows now.
A: I have implemented linux version! I put it in linux branch!
Q: Does it has mutex in reading or writing?
A: No, you can implement mutex by yourself.
A: I have implemented mutex version! Try MutexSharedMemory!
Q: How to create a SharedMemory with specific length, like 10 bytes?
A: Define a struct contian 10 bytes or use char[10] as T.
Example one
struct TenBytes{
char[10] data;
}
SharedMemory<TenBytes> sm("SharedMemory", CREATE_RW);
Example two
SharedMemory<char[10]> sm("SharedMemory", CREATE_RW);
Q: How to create a SharedMemory with initial value?
A: Use constructer to pass initial value!
#include <iostream>
#include "SharedMemory.h"
using namespace std;
using namespace SharedMemoryTemplate;
int main()
{
try{
auto sm = new SharedMemory<int>("SharedMemory", CREATE_RW);
int a = 100;
while (true)
{
sm->write(&a);
cout << a << endl;
a++;
}
}
catch (ErrorCode error)
{
cout << error << endl;
}
system("pause");
return 0;
}
#include <iostream>
#include "SharedMemory.h"
using namespace std;
using namespace SharedMemoryTemplate;
int main()
{
try
{
auto sm = new SharedMemory<int>("SharedMemory", OPEN_RW);
int a = 100;
while (true)
{
sm->read(&a);
cout << a << endl;
}
}
catch (ErrorCode error)
{
cout << error << endl;
}
system("pause");
return 0;
