I suppose I should define lpcfunc as:<br />

I suppose I should define lpcfunc as:

EXEEXPORTPROC *lpcfunc;

but how to define function that retrieves EXE's function pointer?


<div>
It is easy, just have another function defined in DLL:<br />
<br />
setFuncPointer(EXEEXPORTPR<wbr />OC lpcfunc);<br />
<br />
Let the exe call this function and pass the pointer in.<br />

I am making a DLL, that at certain point should call back some function in my main EXE.<br />

How to do this?<br />
<br />
I need a small example of exported DLL function, that will receive information about address of call-back function in EXE, and example of calling call-back function from DLL.<br />

I am using MS VC, and I work in plain C.

CallBack Function

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
