Dear All,

I am using a simple program to access MPI_File attributes. I know that the API provides functions such as MPI_File_get_atomicity( ) but is there a way to access them directly through code?

Example:

int atomicity;

// method 1
printf("atomicity : %d", MPI_File_get_atomicity(fh,&atomicity));

// method 2
printf("atomicity : %d", fh->atomicity);

Method 1 in the above code works fine as expected but method 2 give me the following error 

error: dereferencing pointer to incomplete type

Can anybody guide me on how to solve this problem.

Kind Regards
