Heihei, it\'s a easy task if the two drivers are programmed by yourself.
define a struct with the functions (in the callee) you want to be called by the other driver. struct tagFunctionPtrs { NTSTATUS (*Func1)(argument list); NTSTATUS (*Func2)(argument list); ... ... }; implements a private IOCTL code which can return this function table. In the other driver (caller): 1, IoGetDeviceObjectPointer 2, IoCallDriver with the IOCTL you defined just now So you got the function table now... call these functions as you like... drivers share the same address space, you can do this safely. |
