[Boost-users] serialization::make_nvp parameters

Hello,

I am hoping someone could answer a question I have regarding the
make_nvp(..) function of the Serialization library.

I am attempting to serialize a number of objects within a loop, and the
name of the name-value-pair is to be assigned dynamically depending on
some values taken from within the object that is to be serialized. I am
currently performing the actions below:

my_obj  = GetMyObj(..);

std::string temp = str( boost::format("x:%1% y:%2%") % _x % _y );

const char* const_temp = temp.c_str( );

ar & boost::serialization::make_nvp(const_temp, my_obj);

 

This code compiles but will cause an exception on make_nvp. As far as I
can tell, I am providing the function with the const char* that it
requires, so am very confused as to why it is not performing as
expected.

Any help with this would be greatly appreciated.

 

John Hammond
