Morning,

I`m now using MPI with C++. I`ve already create a datatype and i want to 
commit it. My datatype name is ConDT, i create it with 
MPI::Datatype::Create_struct() and now i want to commit it.
I read on the net that the specification of the commit operation in C++ 
is the follow  void Datatype::Commit() but i could`nt use it. Could any 
one help me?

Thanks!

Why couldn't you use the Commit() method? MPI::Datatype::Create_struct()
returns an instance of MPI::Datatype, which defines this method, so this
should work.
