MPI_Win_get_name(3) MPI MPI_Win_get_name(3) NAME MPI_Win_get_name - Get the print name associated with the MPI RMA win- dow SYNOPSIS int MPI_Win_get_name(MPI_Win win, char *win_name, int *resultlen) INPUT PARAMETERS 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) THREAD AND INTERRUPT SAFETY This routine is thread-safe. This means that this routine may be safely used by multiple threads without the need for any user-provided thread locks. However, the routine is not interrupt safe. Typically, this is due to the use of memory allocation routines such as malloc or other non-MPICH runtime routines that are themselves not interrupt- safe. NOTES FOR FORTRAN All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list. ierr is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the call statement. All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran. ERRORS All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of the function and Fortran routines in the last argument. Before the value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job. The error handler may be changed with MPI_Comm_set_errhandler (for com- municators), MPI_File_set_errhandler (for files), and MPI_Win_set_er- rhandler (for RMA windows). The MPI-1 routine MPI_Errhandler_set may be used but its use is deprecated. 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; however, MPI implementations will attempt to continue when- ever possible. MPI_SUCCESS - No error; MPI routine completed successfully. MPI_ERR_ARG - Invalid argument. Some argument is invalid and is not identi- fied by a specific error class (e.g., MPI_ERR_RANK ). MPI_ERR_WIN - Invalid MPI window object MPI_ERR_OTHER - Other error; use MPI_Error_string to get more information about this error code. 2/3/2025 MPI_Win_get_name(3)
