[−][src]Function close_fds::iter_open_fds

pub fn iter_open_fds(minfd: c_int) -> FdIterⓘ
Notable traits for FdIter
impl Iterator for FdIter    type Item = c_int;

Iterate over all open file descriptors for the current process, starting at minfd. The file descriptors are guaranteed to be returned in ascending order.

Warnings

  1. Some of the file descriptors yielded by this iterator may be in active use by other sections of code. Be very careful about which operations you perform on them.
  2. File descriptors that are opened during iteration may or may not be included in the results (exact behavior is platform-specific and depends on several factors).
  3. Closing file descriptors during iteration will not affect the iterator's ability to list other open file descriptors (if it does, that is a bug). However, in most cases you should use close_open_fds() to do this.
  4. If your program is multi-threaded, this is vulnerable to race conditions; a file descriptor returned by this iterator may not be valid by the time your code tries to do something with it.
