MPI_Win_get_info - Retrieves active window info hints
#include <mpi.h> int MPI_Win_get_info(MPI_Win win, MPI_Info *info_used)
USE MPI ! or the older form: INCLUDE 'mpif.h' MPI_WIN_GET_INFO(WIN, INFO_USED, IERROR) INTEGER COMM, INFO_USED, IERROR
USE mpi_f08 MPI_Win_get_info(win, info_used, ierror) TYPE(MPI_Win), INTENT(IN) :: win TYPE(MPI_Info), INTENT(OUT) :: info_used INTEGER, OPTIONAL, INTENT(OUT) :: ierror
- Window from which to receive active info hints
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.
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.
