MPI_WIN_DUP_FN(3) LAM/MPI MPI_WIN_DUP_FN(3)
MPI_WIN_DUP_FN - Built-in MPI function to simple-mindedly copy window attributes.
int MPI_WIN_DUP_FN(MPI_Win win, int key, void *extra,
void *attrin, void *attrout, int *flag)
win - window (handle)
key - key value (integer)
extra - extra state
attrin - in value for attribute
- out value for attribute
flag - 1 if attribute copied successfully, 0 otherwise (logical)
This function blindly byte-copies attributes on windows. It is the default atrribute-
copying function for windows. This function will always return MPI_SUCCESS , and flag
will always be set to 1.
The actual copy is performed by the code
*((void **) attrout) = attrin;
If this simple assignment is not sufficient for your attributes, you will need to reassign
the attribute-copying function on relevant keyvals on windows with the MPI_Win_keyval_cre-
NOTES FOR FORTRAN
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argu-
ment 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.
For more information, please see the official MPI Forum web site, which contains the text
of both the MPI-1 and MPI-2 standards. These documents contain detailed information about
each MPI function (most of which is not duplicated in these man pages).
The LAM Team would like the thank the MPICH Team for the handy program to generate man
pages ("doctext" from ftp://ftp.mcs.anl.gov/pub/sowing/sowing.tar.gz ), the initial for-
matting, and some initial text for most of the MPI-1 man pages.
