Need to lookup function arguments (in/out) from pdb by dbghelp

Question

I need to lookup function parameters(their types infact) from PDB file

From dbghelp, we can parse any pdb and can get info like how many functions,addresses function names and others etc.

My problem is I am also interested to get function parameters as well. As SYMBOL_INFO structure in callback function only contains symbolName,Addresses and Size. How can we lookup PARAMETERES(in/out Types/names)of any function.
