RkGetYomi — get the reading of the current clause
#include <canna/RK.h> int RkGetYomi(cxnum, yomi, maxyomi) int cxnum; unsigned char *yomi; int maxyomi;
RkGetYomi gets the reading of the current clause and sets it in the area yomi. The resulting character string is truncated when its byte length exceeds maxyomi -1.
This function returns the length of the reading of the current clause, or returns -1, without doing anything, if it has been run in a nonconversion mode context.
