45/// \brief Translate a Clang source range into a CIndex source range.
46///
47/// Clang internally represents ranges where the end location points to the
48/// start of the token at the end. However, for external clients it is more
49/// useful to have a CXSourceRange be a proper half-open interval. This routine
50/// does the appropriate translation.
