Struct nix::poll::PollFlags [−][src]
pub struct PollFlags { /* fields omitted */ }
Expand description
These flags define the different events that can be monitored by poll
and ppoll
Implementations
impl PollFlags
[src]
impl PollFlags
[src]pub const POLLPRI: PollFlags
[src]
pub const POLLPRI: PollFlags
[src]There is some exceptional condition on the file descriptor.
Possibilities include:
- There is out-of-band data on a TCP socket (see tcp(7)).
- A pseudoterminal master in packet mode has seen a state change on the slave (see ioctl_tty(2)).
- A cgroup.events file has been modified (see cgroups(7)).
pub const POLLOUT: PollFlags
[src]
pub const POLLOUT: PollFlags
[src]Writing is now possible, though a write larger that the
available space in a socket or pipe will still block (unless
O_NONBLOCK
is set).
pub const POLLRDNORM: PollFlags
[src]
pub const POLLRDNORM: PollFlags
[src]Equivalent to POLLIN
pub const POLLWRNORM: PollFlags
[src]
pub const POLLWRNORM: PollFlags
[src]Equivalent to POLLOUT
pub const POLLRDBAND: PollFlags
[src]
pub const POLLRDBAND: PollFlags
[src]Priority band data can be read (generally unused on Linux).
pub const POLLWRBAND: PollFlags
[src]
pub const POLLWRBAND: PollFlags
[src]Priority data may be written.
pub const POLLERR: PollFlags
[src]
pub const POLLERR: PollFlags
[src]Error condition (only returned in
PollFd::revents
;
ignored in PollFd::new
).
This bit is also set for a file descriptor referring to the
write end of a pipe when the read end has been closed.
pub const POLLHUP: PollFlags
[src]
pub const POLLHUP: PollFlags
[src]Hang up (only returned in PollFd::revents
;
ignored in PollFd::new
).
Note that when reading from a channel such as a pipe or a stream
socket, this event merely indicates that the peer closed its
end of the channel. Subsequent reads from the channel will
return 0 (end of file) only after all outstanding data in the
channel has been consumed.
pub const POLLNVAL: PollFlags
[src]
pub const POLLNVAL: PollFlags
[src]Invalid request: fd
not open (only returned in
PollFd::revents
;
ignored in PollFd::new
).
pub fn from_bits(bits: c_short) -> Option<PollFlags>
[src]
pub fn from_bits(bits: c_short) -> Option<PollFlags>
[src]Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub const fn from_bits_truncate(bits: c_short) -> PollFlags
[src]
pub const fn from_bits_truncate(bits: c_short) -> PollFlags
[src]Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: c_short) -> PollFlags
[src]
pub const unsafe fn from_bits_unchecked(bits: c_short) -> PollFlags
[src]Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
pub const fn intersects(&self, other: PollFlags) -> bool
[src]
pub const fn intersects(&self, other: PollFlags) -> bool
[src]Returns true
if there are flags common to both self
and other
.
