[issue12898] add opendir() for POSIX platforms

Larry Hastings added the comment: fdlistdir() is largely irrelevant to the discussion. I was proposing adding a function to open directory fds, because there isn't one; fdlistdir(), like many other POSIX functions available in Python, consumes directory fds. -- _

[issue12898] add opendir() for POSIX platforms

Larry Hastings added the comment: Well, there's no os.fdopendir(); I think you're referring to fdlistdir(), which uses the C function fdopendir() internally. The DIR structure is not exposed to the Python caller at any point. I did miss the whole opendir-returns-a-DIR-not-a-fd thing, hopeful

[issue12898] add opendir() for POSIX platforms

Ross Lagerwall added the comment: opendir opens a C dirent structure with an underlying file descriptor. However, to open a directory file descriptor, simple use: os.open("/tmp", os.O_RDONLY) This can then be used as the fd to the functions which require a directory fd like os.openat() Chee

[issue12898] add opendir() for POSIX platforms

New submission from Larry Hastings : With the recent spate of POSIX *at() functions added to os, we now have a bunch of places in the API that take directory fds. But afaict there's no way to get a directory fd in Python! The only calls to opendir() in the tree are internal, in os.listdir()

[issue12898] add opendir() for POSIX platforms

Ross Lagerwall added the comment: Also see fdopendir(3) which allows you to pass an open file descriptor to get a C dirent struct. This is implemented in the os module too but instead of returning a struct, it returns a list. -- ___ Python tracker
