Generally, each application has its own data segment. This mearn they are independent where two applications use a dll together. But, sometimes, we want to know what other applications are doing. So we want used a shared memory. There are many ways to do so, use a shared DLL section is one of them.
Following is the simply step to create a shared memory.
1. Create a DLL project.
2. Create a segment named �.shared�, and create shared members at this section.
#pragma data_seg(".shared")
char theBuffer[1024] = "";
#pragma data_seg()
3. Define this section as shared. This is defined at TheDll.def file.
SECTIONS
.shared READ WRITE SHARED
