DoEvents in C++

In VisualC++ I have a program that calls DoEvents() and works just fine.  

I moved the exact same code outside VisualC++, since I need it as a stand alone program.  However, my DoEvents() now do cause linkage problems.  These look like:

void DoEvents(void)
    MSG msg;

DoEvents processes Windows Messages in the message queue. C++ does not have a one command counterpart. What can I do?  I need a DoEvents in plain C++!  Anyone knows?

DoEvents is just a function defined in a windows library, VC++ probably just automatically includes the library header, and link the library in when compiling/linking.

Basically when you compile (example here is for the GNU c++ compiler)

g++ yourprogram.cpp -o yourprogram.exe -lKernel32

The -lKernel32 means link to the Kernel32 library.

I think Kernel32 is the right library for DoEvents, check it and lemme know if it works.

Dear UncleJimbo,

Kernel32.LIB did not work but User32.LIB did.  Thanks to your comment I got a better idea about which library to include.
