NAME¶
MPI_Win_get_name - Obtains the name of a window.
C Syntax¶
#include <mpi.h>
int MPI_Win_get_name(MPI_Win win, char *win_name, int *resultlen)
Fortran Syntax¶
INCLUDE 'mpif.h'
MPI_WIN_GET_NAME(WIN, WIN_NAME, RESULTLEN, IERROR)
INTEGER WIN, RESULTLEN, IERROR
CHARACTER*(*) WIN_NAME
C++ Syntax¶
#include <mpi.h>
void MPI::Win::Get_name(char* win_name, int& resultlen) const
- win
- Window whose name is to be returned (handle).
OUTPUT PARAMETERS¶
- win_name
- the name previously stored on the window, or an empty string if no such
name exists (string).
- resultlen
- Length of returned name (integer).
- IERROR
- Fortran only: Error status (integer).
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.
