Memory allocation in modules created for apache 1.3.27

Hello, I am writing a little C module for Apache 1.3.27 for Solaris.
I was wondering if I need to worry about memory de-allocation after
I've made a call to "ap_pstrdup" for the purposes of creating a new
character array. I've looked over the documentation and I can't seem
to find such a de-allocation function. So I turn to the experts.

Thanks for your advice, - Dave
