MPI_File_iwrite_at(3)MPI_File_iwrite_at(3)NAMEMPI_File_iwrite_at - Performs a nonblocking write using an explict offset
SYNOPSIS
C:
#include "mpi.h"
int MPI_File_iwrite_at(MPI_File fh, MPI_Offset offset,
void *buf, int count, MPI_Datatype datatype, MPI_Request
*request)
Fortran:
INCLUDE "mpif.h" (or USE MPI)
<type> BUF(*)
INTEGER fh, count, datatype, request, ierror
INTEGER(KIND=MPI_OFFSET_KIND) offset
CALL MPI_FILE_IWRITE_AT(fh, offset, buf, count,
datatype, request, ierror)
DESCRIPTIONMPI_File_iwrite_at is a nonblocking version of the MPI_FILE_WRITE_AT
interface.
MPI_File_iwrite_at accepts the following arguments:
fh Specifies the file handle (handle)
offset Specifies the file offset (nonnegative integer)
buf Specifies the initial address of the buffer (choice)
count Specifies the number of elements in the buffer (nonnegative
integer)
datatype Specifies the datatype of each buffer element (handle)
request Returns the request object (handle)
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.
