C synopsis

#include <mpi.h>
MPI_Win MPI_Win_f2c(MPI_Fint win);

Parameters

win

is the window (handle) (IN)

Description

This function does not have C++ or FORTRAN bindings. MPI_Win_f2c returns a C handle to a window. If win is a valid FORTRAN handle to a window, MPI_Win_f2c returns a valid C handle to that same window. If win is set to the FORTRAN value MPI_WIN_NULL, MPI_Win_f2c returns the equivalent null C handle. If win is not a valid FORTRAN handle, MPI_Win_f2c returns a non-valid C handle. The converted handle is returned as the function's value. There is no error detection or return code.

Errors

None.
