Function posish::io::is_read_write [−][src]
pub fn is_read_write<Fd: AsUnsafeHandle>(fd: &Fd) -> Result<(bool, bool)>
Returns a pair of booleans indicating whether the file descriptor is readable
and/or writeable, respectively. Unlike is_file_read_write
, this correctly
detects whether sockets have been shutdown, partially or completely.
