Creating Named Shared Memory (From MSDN: [url]http://msdn.microsoft.com/library/en-us/fileio/base/creating_named_shared_memory.asp?frame=true[/url])
Multiple processes can use memory-mapped files that are backed by the system paging file to share data.
First Process
The first process creates the file mapping object by calling the CreateFileMapping function with INVALID_HANDLE_VALUE and a name for the object. By using the PAGE_READWRITE flag, the process will have read/write permission to the memory through any file views that are created.
The process then uses the file mapping object handle returned by CreateFileMapping in the call to MapViewOfFile to create a view of the file in the process address space. The MapViewOfFile function returns a pointer to the file view.
When the process no longer needs access to the file-mapping object, it should call the CloseHandle function. When all handles are closed, the system can free the section of the paging file used by the object.
[PHP]
#include <windows.h>
#include <stdio.h>
#include <conio.h>
#define BUF_SIZE 256
TCHAR szName[]=TEXT("MyFileMappingObject");
TCHAR szMsg[]=TEXT("Message from first process");
void main()
{
HANDLE hMapFile;
LPCTSTR pBuf;
hMapFile = CreateFileMapping(
INVALID_HANDLE_VALUE, // use paging file
NULL, // default security
PAGE_READWRITE, // read/write access
0, // max. object size
BUF_SIZE, // buffer size
szName); // name of mapping object
if (hMapFile == NULL || hMapFile == INVALID_HANDLE_VALUE)
{
printf("Could not create file mapping object (%d).\n", GetLastError());
return;
}
pBuf = (LPTSTR) MapViewOfFile(hMapFile, // handle to mapping object
FILE_MAP_ALL_ACCESS, // read/write permission
0,
0,
BUF_SIZE);
if (pBuf == NULL)
{
printf("Could not map view of file (%d).\n", GetLastError());
return;
}
CopyMemory((PVOID)pBuf, szMsg, strlen(szMsg));
getch();
UnmapViewOfFile(pBuf);
CloseHandle(hMapFile);
}
[/PHP]
Second Process
A second process can access the same data by calling the OpenFileMapping function with the same name as the first process. It can then use the MapViewOfFile function to obtain a pointer to the file view.
[PHP]
#include <windows.h>
#include <stdio.h>
#include <conio.h>
#define BUF_SIZE 256
TCHAR szName[]=TEXT("MyFileMappingObject");
void main()
{
HANDLE hMapFile;
LPCTSTR pBuf;
hMapFile = OpenFileMapping(
FILE_MAP_ALL_ACCESS, // read/write access
FALSE, // do not inherit the name
szName); // name of mapping object
if (hMapFile == NULL)
{
printf("Could not open file mapping object (%d).\n", GetLastError());
return;
}
pBuf = MapViewOfFile(hMapFile, // handle to mapping object
FILE_MAP_ALL_ACCESS, // read/write permission
0,
0,
BUF_SIZE);
if (pBuf == NULL)
{
printf("Could not map view of file (%d).\n", GetLastError());
return;
}
MessageBox(NULL, pBuf, TEXT("Process2"), MB_OK);
UnmapViewOfFile(pBuf);
CloseHandle(hMapFile);
}
