MPI_File_write_at(3) MPI MPI_File_write_at(3)
NAME
MPI_File_write_at - 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. 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.
