NAME¶
MPI_Win_get_info - Retrieves active window info hints
C Syntax¶
#include <mpi.h>
int MPI_Win_get_info(MPI_Win win, MPI_Info *info_used)
Fortran Syntax¶
INCLUDE 'mpif.h'
MPI_WIN_GET_INFO(WIN, INFO_USED, IERROR)
INTEGER COMM, INFO_USED, IERROR
- win
- Window from which to receive active info hints
OUTPUT PARAMETERS¶
- info_used
- New info object returned with all active hints on this window.
- IERROR
- Fortran only: Error status (integer).
DESCRIPTION¶
MPI_Win_get_info returns a new info object containing the hints of the window
associated with win. The current setting of all hints actually used by
the system related to this window is returned in info_used. If no such
hints exist, a handle to a newly created info object is returned that contains
no key/value pair. The user is responsible for freeing info_used via
MPI_Info_free.
ERRORS¶
Almost all MPI routines return an error value; C routines as the value of the
function and Fortran routines in the last argument.
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.
