Write using explict offset

Synopsis

int MPI_File_write_at(MPI_File mpi_fh, MPI_Offset offset, void *buf,
                      int count, MPI_Datatype datatype, 
                      MPI_Status *status)

Input Parameters

fh: file handle (handle)

offset: file offset (nonnegative integer)

buf: initial address of buffer (choice)

count: number of elements in buffer (nonnegative integer)

datatype: datatype of each buffer element (handle)

Output Parameters

status: status object (Status)

Notes for Fortran

All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK) have an additional argument ierr at the end of the argument list. ierris an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the call statement.

All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type INTEGERin Fortran.
