Hi all,
I am looking for a solution in c++. I.e. At runtime how I can get
the function pointers which is existing in the object. Will it be possible to invoke a function dynamically through a string that contains it's(function) name.
Regards,
PMS.

The best solution I can think of is to have a method within the class that maps a string to a function, and have it called through there.

The details regarding where a function is stored is not available in an object always. When a class contains no virtual fns, the address resolution of the functions happen at compile time and i dont think you have an API to access that.
The scenario is different when there are virtual fns in a class. Every object contains a pointer to the virtual function table. The address of the function to be called is calculated at run time in an implementaion dependent way. you might try out on your implementation how it is actually done.
