How to get the name of the function called by a * to a function

Hi all,
I was still playing with the Interpreter class and I was wondering if it is possible to obtain the reference to the function that would be called by a * to a function.

For instance:

%2 = load {}, {}** %1, align 8
…
%5 = bitcast {} %2 to void (%struct.png_struct_def.129*, i8*, i64)*
tail call void %5(%struct.png_struct_def.129* %png_ptr, i8* %data, i64 %length) #15

Once I encounter the call instruction, can I find out which function will be called before actually performing the call?

I hope it is clear :slight_smile:

Thanks
Alberto
