What is the functionality of get_full_list and its parameters does

Hi Team

This is exactly what i needed. can you please explain following line of code ? 

get_full_list(null,'(name != "Foo Bar" )',true);

can't understand the parameters, null, true, and  '(name != "Foo Bar" )'. wasn't it an array of string fields ? 

Regards
