Compiler Warning (level 1) C4835

'variable' : the initializer for exported data will not be run until managed code is first executed in the host assembly

Remarks

When accessing data between managed components, it is recommended that you not use native C++ import and export mechanisms. Instead, declare your data members inside a managed type and reference the metadata with #using in the client. For more information, see #using Directive.

Examples

The following example generates C4835.

// C4835.cpp
// compile with: /W1 /clr /LD
int f() { return 1; }
int n = 9;

__declspec(dllexport) int m = f();   // C4835
__declspec(dllexport) int *p = &n;   // C4835

The following example consumes the component built in the previous example, showing that the value of the variables is not as expected.

// C4835_b.cpp
// compile with: /clr C4835.lib
#include <stdio.h>
__declspec(dllimport) int m;
__declspec(dllimport) int *p;

int main() {
   printf("%d\n", m);
   printf("%d\n", p);
}
