Most, if not all,Á üñI F functions directly relate to the equivalent system call with no errorÁ ü»P M handling applied, so no handling errors such as [`EINTR`]. As a result usingÁ üŒ P M this crate can be a little wordy, but it should give you maximal flexibilityÁ üÝ " over configuration of sockets.Á €

If `timeout` in milliseconds is larger than `c_uint::MAX`, the timeout is clampedÁ üŸ�^ [ to `c_uint::MAX`. For example, when `c_uint` is a 32-bit value, this limits the timeout toÁ ì‚‚ approximately 49.71 days.Á »£|·‚úŒ ¬á‚úÊ ¬„ƒúò œ§ƒú«
