I read some examples either to open file/ set file view[1][2] or to use struct data type[3] only. How if a developer wants to set file view with struct data type (as file type)? I notice that mpi_set_view requires parameters `MPI_Datatype etype, MPI_Datatype filetype.' However, for struct data type, it has multiple elementary types (ARRAY_OF_TYPES). How can a developer determine which data type is the elementary type in view? In addition, is it necessary (or a must have step) to set view if one decides to open file?
