EXPORT_SYMBOL() for Windows drivers

Is there any WDM mechanism, similar to EXPORT_SYMBOL under Linux, such that one can use symbols from a driver (A.sys) in another driver (B.sys)?

This is same mechanism as user mode, basically drivers are same PE images as user mode. Simplest approach to mark functions that you wish to export as _declspec(dllexport). And add to header definition _declspec(dllimport):

_declspec(dllexport) void ExportSymbol1(void); void ExportSymbol1(void) { KdPrint(("exported call\n")); }

and

_declspec(dllimport) void ExportSymbol1(void);

Also you can use export driver approach (http://msdn.microsoft.com/en-us/library/windows/hardware/ff542891(v=vs.85).aspx)
