Good APR example code

[Mark Jones]

Hello All

 I am thinking about using APR in a project. Are there any source for good 
example code using APR I have seen a few examples but all of them only seem 
to show the use of sockets with APR. I am very intersted in what APR can do 
on the multithread/process/IPC department. I guess of course I could always 
look at the apache code.

Thanks
Mark
