There was a problem hiding this comment.
TIL that closedir(NULL) causes some sort of abort on macOS, but not on Linux.

This API enables iteration of large directories. There are three parts here:
It's worth discussing the reason I created the
rcutils_dir_iter_state_tstruct instead of putting more stuff inrcutils_dir_iter_t. The biggest motivating factor there is that we needwindows.hfor those types, and I REALLY REALLY don't want that polluting our rcutils headers. Additionally, the idea behind this API is to hide the platform-specific data structures, so that stuff is essentially private data for the API.Closes #249
