Accessor +functions should be provided to get at the fields within each structure, +because the actual internals should be different on each OS. + +When creating a function for any OS, please keep in mind that this is being +designed as a PORTABLE run-time. If there is a function that only one OS +implements, and it is IMPOSSIBLE to emulate on any other system. Make a note +about it in the comments, but please do not add the function. When other OS's +can implement the same function, it should be added to APR. We do not want +functions to do different things on different platforms from the get-go though. + We try to look like POSIX where possible, but the first design goal is a clean API without a lot of overhead.
