Synopsis

int MPI_File_write_at_all_begin(MPI_File mpi_fh, MPI_Offset offset, void *buf,
                             int count, MPI_Datatype datatype)

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)

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. ierr is 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 INTEGER in Fortran.
