MPI_File_read_at(3)					   MPI_File_read_at(3)

NAME
     MPI_File_read_at - Uses explicit offset to perform a read operation

SYNOPSIS
     C:

	  #include "mpi.h"

	  int MPI_File_read_at(MPI_File fh, MPI_Offset offset, void
	  *buf, int count, MPI_Datatype datatype, MPI_Status
	  *status)

     Fortran:

	  INCLUDE "mpif.h" (or USE MPI)

	  <type> BUF(*)
	  INTEGER fh, count, datatype, status(MPI_STATUS_SIZE),
	  ierror
	  INTEGER(KIND=MPI_OFFSET_KIND) offset

	  CALL MPI_FILE_READ_AT(fh, offset, buf, count,
	  datatype, status, ierror)

DESCRIPTION
     MPI_File_read_at reads a file beginning at the position specified by
     offset. This routine accepts the following arguments:

     fh	       Specifies the file handle (handle)

     offset    Specifies the file offset (nonnegative integer)

     buf       Returns the initial address of the buffer (choice)

     count     Specifies the number of elements in the buffer (nonnegative
	       integer)

     datatype  Specifies the data type of each buffer element (handle)

     status    Returns the status object (status)

     ierror    Specifies the return code value for successful completion,
	       which is in MPI_SUCCESS.	 MPI_SUCCESS is defined in the mpif.h
	       file.

   Notes for Fortran
     All MPI objects (for example, MPI_Datatype, MPI_Comm, MPI_File) are of
     type INTEGER.
