Passing fstream to function as structure member

Question

I have following structure,

struct option
{   
    std::fstream fpointer;
    char* clifn;
};

I want to pass this structure as argument to another function (other way is to pass individual element and fpointer as reference), passing it to function throws a compiler error

error C2248: 'std::basic_fstream<_Elem,_Traits>::basic_fstream' : cannot access private member declared in class 'std::basic_fstream<_Elem,_Traits>'

is there any way to pass std::fstream object of struct member to function.

Answer 1

Streams are not copyable so struct option is therefore not copyable because it has a non-copyable member (fpointer). Pass struct option by reference to avoid the copy:

void some_function(option& a_option)
{
}
