Adds the specified symbol to the symbol table and returns a reference to the unique symbol. If the symbol already exists, the previous symbol reference is returned instead, in order guarantee that symbol references remain unique.
Params:

Adds the specified symbol to the symbol table and returns a reference to the unique symbol. If the symbol already exists, the previous symbol reference is returned instead, in order guarantee that symbol references remain unique.
Params:
  • buffer – The buffer containing the new symbol.
  • offset – The offset into the buffer of the new symbol.
  • length – The length of the new symbol in the buffer.
