NAME¶
MPI_Win_c2f - Convert a window handle from its C representation to its Fortran
representation
SYNOPSIS¶
#include <mpi.h>
MPI_Fint
MPI_Win_c2f(MPI_Win win)
RETURN VALUE¶
- f_handle
- - Fortran window handle
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¶
This function does not return the normal MPI_SUCCESS integer value upon
success. Instead, it returns a handle to the converted object. If an error
occurs, the appropriate NULL handle will be returned.
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).
