NAME
MPI_File_iwrite_shared - Writes a file using the shared file pointer
(nonblocking, noncollective).
SYNTAX
C Syntax
#include <mpi.h>
int MPI_File_(MPI_File fh, void *buf, int count, MPI_Datatype
datatype, MPI_Request *request)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_File_(FH, BUF, COUNT, DATATYPE, REQUEST, IERROR)
<type> BUF(*)
INTEGER FH, COUNT, DATATYPE, REQUEST, IERROR
C++ Syntax
#include <mpi.h>
MPI::Request MPI::File::Iwrite_shared(const void* buf, int count,
const MPI::Datatype& datatype)
INPUT/OUTPUT PARAMETER
fh File handle (handle).
INPUT PARAMETERS
count Number of elements in buffer (integer).
datatype Data type of each buffer element (handle).
OUTPUT PARAMETERS
buf Initial address of buffer (choice).
request Request object (handle).
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_File_iwrite_shared is a nonblocking routine that uses the shared
file pointer to write files. The order of serialization is not deter-
ministic for this noncollective routine, so you need to use other meth-
ods of synchronization to impose a particular order.
ERRORS
Almost all MPI routines return an error value; C routines as the value
of the function and Fortran routines in the last argument. C++ func-
tions do not return errors. If the default error handler is set to
MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
will be used to throw an MPI:Exception object.
