[LLVMdev] Question about function arguments

Hello All,
I was wondering how I could determine the values of function arguments using
the iterators defined in Function.cpp.
Any advice or hints would be great..!
Basically, what I am trying out is:
Function foo has the following function body:
int foo(int a, int b) {
}
Function * f = module->getFunction("foo");
Function::arg_iterator start = f->arg_begin();
Function::arg_iterator end = f->arg_end();
while(start != end) {
Argument * value = (Argument *)start;
cout << "\n Argument: << value->getNameStr();
start++;
}
This piece of code works if 'module' contains the definition of function
foo. Otherwise, I just get blanks even though the number returned by
arg_size() is two.
If foo is just a function being called from 'module', then how do I
determine the arguments.

Hemanth
