Function iter_possible_fds_threadsafe 

pub fn iter_possible_fds_threadsafe(minfd: c_int) -> FdIter 

Identical to iter_open_fds_threadsafe(), but may – for efficiency – yield invalid file descriptors.

This is equivalent to FdIterBuilder::new().possible(true).threadafe(true).iter_from(minfd).

See FdIterBuilder::possible() and FdIterBuilder::threadsafe() for more information.
