Function rfind

include/win/boost/container/string.hpp:1997–1998

Effects : Determines the highest position xpos, if possible, such that both of the following conditions obtain: a) xpos <= pos and xpos + str.size() <= size(); b) traits::eq(at(xpos+I), str.at(I)) for all elements I of the string controlled by str. Throws : Nothing Returns : xpos if the function can determine such a value for xpos. Otherwise, returns npos.

   //!
   //! <b>Returns</b>: xpos if the function can determine such a value for xpos. Otherwise, returns npos.
   size_type rfind(const basic_string& str, size_type pos = npos) const
      { return rfind(str.c_str(), pos, str.size()); }

   //! <b>Requires</b>: s points to an array of at least n elements of CharT.
