MPI_DUP_FN - Built-in MPI function to simple-mindedly copy communicator attributes.
#include <mpi.h> int MPI_DUP_FN(MPI_Comm comm, int key, void *extra, void *attrin, void *attrout, int *flag)
comm - communicator (handle) key - key value (integer) extra - extra state attrin - in value for attribute
attrout - out value for attribute flag - 1 if attribute copied successfully, 0 otherwise (logical)
This function is deprecated. It has been replaced with an MPI-2 function (see the "See also" section, below), which provides the same functionality. This function is (or effectively is) a wrapper to the replacement function, anyway. User programs should use the MPI-2 replacement function instead of this function. Some functions are deprecated because their names did not conform to the stricter naming conventions of MPI-2; others are deprecated because they have been replaced with more flexible functionality.
Note that the C typedefs MPI_Copy_function and MPI_MPI_Delete_function are also deprecated, in favor of their new names - MPI_Comm_copy_function , MPI_Comm_delete_function . Additionally, the MPI constants MPI_NULL_COPY_FN and MPI_NULL_DELETE_FN are also deprecated in favor of their new names - MPI_COMM_NULL_COPY_FN and MPI_COMM_NULL_DELETE_FN .
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). http://www.mpi-forum.org/
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.
