NAME
RkXfer - change the current candidate
SYNOPSIS
#include <canna/RK.h>
int RkXfer(cxnum, knum)
int cxnum;
int knum;
DESCRIPTION
RkXfer sets the candidate with a specified candidate number knum as the
current candidate. The candidate number must be 0 or greater but less
than the highest candidate number in the current clause. The current
clause does not change when a candidate number outside this range is
specified.
RETURN VALUE
If successful, this function moves the current candidate in the context
and returns the candidate number after the move. It returns 0, without
doing anything, if it has been run in a nonconversion mode context.
