Yes the function is exported. Please confirm if this is correct way of doing
it.

typedef int (*MYPROC)(unsigned int);

HINSTANCE hinstLib;
MYPROC ProcAdd;
unsigned int retVal = 0;

        hinstLib = LoadLibrary("Server_dll.dll");
        if(hinstLib != NULL)
        {
            ProcAdd = (MYPROC) GetProcAddress(hinstLib,
TEXT("MyDllFunction"));
            if (NULL != ProcAdd)
           {
               _asm
               {
                    call ProcAdd
                    mov retVal, eax
               }
            }
            FreeLibrary(hinstLib);
        }

If I'm right, will I get the return value of that Dll function in retVal
variable.

MyDllFunction(unsinged int)

In my MFC application, I've added a link to its lib file and also
included
its header file in my MFC app Cpp file. When I call this function, I get
a
linking error saying that

unresolved external symbol "struct hdr * __cdecl MyDllFunction(unsigned
int)

Where am I going wrong??

Is this function exported? You can use Depends.exe to see what all
functions from this dll are exported.
