Win32 DLLs are mapped into the address space of the calling process. By default, each process using a DLL has its own instance of all the DLLs global and static variables. (娉ㄦ剰: 鍗充嬌鏄叏灞鍙橀噺鍜岄潤鎬佸彉閲忎篃閮戒笉鏄叡浜殑!) If your DLL needs to share data with other instances of it loaded by other applications, you can use either of the following approaches:
· Create named data sections using the data_seg pragma.
· Use memory mapped files. See the Win32 documentation about memory mapped files.
Here is an example of using the data_seg pragma:
#pragma data_seg (".myseg")
int i = 0;
char a[32] = "hello world";
#pragma data_seg()
data_seg can be used to create a new named section (.myseg in this example). The most typical usage is to call the data segment .shared for clarity. You then must specify the correct sharing attributes for this new named data section in your .def file or with the linker option /SECTION:.MYSEC,RWS. (榪欎釜緙栬瘧鍙傛暟鏃㈠彲浠ヤ嬌鐢╬ragma鎸囦護鏉ユ寚瀹氾紝涔熷彲浠ュ湪VC鐨処DE涓寚瀹氾紒)
There are restrictions to consider before using a shared data segment:
· Any variables in a shared data segment must be statically initialized. In the above example, i is initialized to 0 and a is 32 characters initialized to hello world.
· All shared variables are placed in the compiled DLL in the specified data segment. Very large arrays can result in very large DLLs. This is true of all initialized global variables.
· Never store process-specific information in a shared data segment. Most Win32 data structures or values (such as HANDLEs) are really valid only within the context of a single process.
· Each process gets its own address space. It is very important that pointers are never stored in a variable contained in a shared data segment. A pointer might be perfectly valid in one application but not in another.
· It is possible that the DLL itself could get loaded at a different address in the virtual address spaces of each process. It is not safe to have pointers to functions in the DLL or to other shared variables.
