title: (Ida Pro) Find out which functions use the import symbol
body: <p>I am new to Ida and I need to use it to identify which functions within the executable call one of these. I am trying to find a way a packet is encrypted as a security exercise. Lets say I want to look at the imports window and see these, does that mean that those are the only functions referenced in the executable?
  How can I find where sendto is referenced? I tried to search it by name but the search takes forever and does not seem to find anything.</p>
