Thanks Stephen.
I have a CPP file which has been programmed by another programmer (Say A
).
This CPP file has a member function ( fun of class test ) which accepts
the parameters of the function
PEM_read_bio_PKCS8_PRIV_KEY_INFO(SAME_PARAMETERS)
[
that is fun is defined like this
fun(SAME_PARAMETERS)
{
//some stuff
}
]
Now I am not supposed to modify A's code and I am calling that function
using that class's (test's ) object.
What I need to know is how the parameters should be initialized before
passing values to that function (fun of class test ).
Of course we can override that function with another class inheriting
the class test and making my own implementation of a function calling
PEM_read_bio_PrivateKey.
But for this case I need to repeat the process what has been implemented
in the function fun.
One more thing is that I need the source code of programmer A.
Another issue is that, if in future Programmer A changes his source code
I need to do the same in my own implementation of that function (fun).
But as I have mentioned in the previous mail, I want to use this
function (fun of class test ) in my program
Thanks,
Murugesan
