NAME
MPI_Win_get_group - Returns a duplicate of the group of the communicator used to create the window.SYNTAX
C Syntax
#include <mpi.h> MPI_Win_get_group(MPI_Win win, MPI_Group *group)
Fortran Syntax
INCLUDE 'mpif.h' MPI_WIN_GET_GROUP(WIN, GROUP, IERROR) INTEGER WIN, GROUP, IERROR
C++ Syntax
#include <mpi.h> MPI::Group MPI::Win::Get_group() const
INPUT PARAMETER
- win
- Window object (handle).
OUTPUT PARAMETERS
- group
- Group of processes that share access to the window (handle).
- IERROR
- Fortran only: Error status (integer).
DESCRIPTION
MPI_Win_get_group returns a duplicate of the group of the communicator used to create the window associated with win. The group is returned in group.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. 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.
