NAME
MPI_File_read_at - Read using explict offset
SYNOPSIS
#include "mpi.h" int MPI_File_read_at(MPI_File 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) count - number of elements in buffer (nonnegative integer) datatype - datatype of each buffer element (handle)
OUTPUT PARAMETERS
buf - initial address of buffer (choice) 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', 'MPI_File') are of type 'INTEGER' in Fortran. 8/31/1998 MPI_File_read_at(3)
