During compilation different common section will be placed in OBJ file. You can make smaller, more-independent apps with the help of a "mini-CRT" Library. It's very important, that program executable (EXE or DLL) contains not only from the code, but it has many additional information in the header part of the PE. All of the C language and most of the basic C++ language infrastructure is provided in MSVCRT(D).dll. Check This Out

It is possible to link a program requiring _chkstk() by providing your own implementation, but since this will not perform the required stack touching, the program will always crash! However, lstrcpynA/W() has subtly different semantics to strncpy()/wcsncpy(), which can lead to some nasty bugs. All of these functions can replace their C Standard counterparts: strcat()/wcscat(), strcmp()/wcscmp(), stricmp()/wcsicmp(), strcpy()/wcscpy(), strncpy()/wcsncpy() and strlen()/wcslen().

Visual Studio complains about unresolved external symbols. I am mainly an Unix user so I might be mistaken there. For this reason, and from bitter personal experience, I recommend that you steer clear of this function entirely. You are now compiling the full flow!! In this case, the DLL indeeds contains undefined symbols because we expect the DLL to find those symbols within the EXE file.

Linking statically to the CRT Library always increases the size of the application/library, sometimes dramatically so, particularly when building small application/libraries. The code in Listing 2 is an extract from the Visual C++ 6.0 CRT implementation, and you would need to include something similar in your application to ensure consistency.

CRT Global Variables The global variables, such as errno, _osver, _winmajor, _winminor, _winver, _pgmptr, _wpgmmptr, _environ, and so on, are all set up and manipulated by the CRT Library (see "Special

For C++ components, it handles the C++ language infrastructure, such as the construction and destruction of static objects. The signature of the function is as follows: extern "C" void __declspec(naked) __cdecl _chkesp(void); If you can write code without precipitating the insertion of _chkesp(), then you needn't worry. Note that HeapRealloc() does not support the semantics of realloc() in regards to being passed a Null memory block pointer, hence the conditional tests. In some seldom situations you do can export data or functions from EXE.

The third option is to use the #pragma intrinsic statement, which applies intrinsic on a function-by-function basis.
