How to get contents of symbol table?

Hi there!, I'm looking for a way to loop through the symbol table. In other words I want to be able to loop through every variable defined in the local scope. I've looked through the manual, but either I couldn't find a function which can do this or I wasn't looking in the right place. If anyone can point me in the right direction that would be great!
