#define TheVLM(x) VLM::Global()->x TheVLM(Run());

What does t开发者_开发百科his mean in C++:

#define TheVLM(x) VLM::Global()->x TheVLM(Run());

Are you sure it's not on two lines, like :

#define TheVLM(x) VLM::Global()->x 
TheVLM(Run());

In that case, it's nothing specfic to C++, it is a standard use of Macro. The second line will generate the following call after macro substitution:

VLM::Global()->Run();
