MPI_WIN_DUP_FN - Built-in MPI function to simple-mindedly copy window
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_create function.
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
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
formatting, and some initial text for most of the MPI-1 man pages.
