|count||Maximum number of elements to receive (integer).|
|datatype||Type of each entry (handle).|
|source||Rank of source (integer).|
|tag||Message tag (integer).|
buf Initial address of receive buffer (choice).
request Communication request (handle). IERROR Fortran only: Error status (integer).
Creates a persistent communication request for a receive operation. The argument buf is marked as OUT because the user gives permission to write on the receive buffer by passing the argument to MPI_Recv_init.
A persistent communication request is inactive after it is created -- no active communication is attached to the request.
A communication (send or receive) that uses a persistent request is initiated by the function MPI_Start or MPI_Startall.
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.
