issue in converting a parameter to reference

Hi,

Please forgive me for my basic c++ knowledge.

I tried to change one of the parameters of the c++ function to reference (7th parameter of type BearerQOSInfo) , I am getting the following compile error..This may be minor issue but i have been staring at this for sometime.. I hope c++ gurus give me some quick inputs, and is greatly appreciated.

I just changed the parameter "BearerQOSInfo" to reference type.

But now getting the following error, even after changing the function prototype to reflect this.

ransrc/CPGW.cpp:1158: error: no matching function for call to 'CDiaConnection::SendGxDiaCCOnSession(std::string&, RANType, int, u32&, std::string&, u32&, const BearerQoSInfo&, std::string&)'

The prototype in the header file looks like this:
ransrc/Diameter.h:481: note: candidates are: static void CDiaConnection::SendGxDiaCCOnSession(const std::string&, RANType, u8, u32, std::string&, u32, BearerQoSInfo&, std::string)

Thanks in advance for the quick inputs

Looks like the issue is resolved now, (not sure why changing the paramter to reference also needed to change the declaration to the const)..

Anyway thanks a lot ...
