- buf
- Initial address of send buffer (choice).
- count
- Number
of elements in send buffer (nonnegative integer).
- datatype
- Datatype of each
send buffer element (handle).
- dest
- Rank of destination (integer).
- tag
- Message
tag (integer).
- comm
- Communicator (handle).
- IERROR
- Fortran
only: Error status (integer).
MPI_Ssend performs a synchronous-mode,
blocking send. See the MPI-1 Standard for more detailed information about
such sends.
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. By default, this error
handler aborts the MPI job, except for I/O function errors. The error handler
may be changed with MPI_Comm_set_errhandler; the predefined error handler
MPI_ERRORS_RETURN may be used to cause error values to be returned. Note
that MPI does not guarantee that an MPI program can continue past an error.
