 datatype, MPI_Request *request)


 Fortran Syntax

 <type> BUF(*)
 INTEGER FH, COUNT, DATATYPE, REQUEST, IERROR


 Fortran 2008 Syntax

 1i
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 deterministic for this noncollective routine, so you need to use other methods 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++ functions 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.
Before the error value is returned, the current MPI error handler is
called. For MPI I/O function errors, the default error handler is set to MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler; the predefined error handler MPI_ERRORS_ARE_FATAL may be used to make I/O errors fatal. Note that MPI does not guarantee that an MPI program can continue past an error.
