## 2.5.7. File Offsets

Up: Data Types Next: Language Binding Previous: Addresses

For I/O there is a need to give the size, displacement, and offset into a file. These quantities can easily be larger than 32 bits which can be the default size of a Fortran integer. To overcome this, these quantities are declared to be `INTEGER (KIND=MPI_OFFSET_KIND)` in Fortran. In C one uses MPI_Offset whereas in C++ one uses MPI::Offset.
