MPI_File_read_all(3)

NAME
     MPI_File_read_all - Uses individual file pointer to perform a collective
     read

SYNOPSIS
     C:

          #include "mpi.h"

          int MPI_File_read_all(MPI_File fh, 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

          CALL MPI_FILE_READ_ALL(fh, buf, count, datatype,
          status, ierror)


DESCRIPTION
     MPI_File_read_all is a collective version of the blocking MPI_File_read
     interface. MPI_File_read_all accepts the following arguments:

     fh        Specifies the file handle (handle)

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

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

     buf       Returns the initial address of the buffer (choice)

     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.
