MPI_File_write - Write using individual file pointer
SYNOPSIS
C:
#include "mpi.h"
int MPI_File_write(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_WRITE(fh, buf, count, datatype,
status, ierror)
DESCRIPTION
MPI_File_write writes a file using the individual file
pointer.
MPI_File_write accepts the following arguments:
fh Specifies the file handle (handle)
buf Specifies 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.
