method native-descriptor
Documentation for method native-descriptor
assembled from the following types:
class IO::CatHandle
From IO::CatHandle
(IO::CatHandle) method native-descriptor
Defined as:
method native-descriptor(IO::CatHandle: --> Int)
Returns the native-descriptor of the currently active source handle or Nil if the source handle queue has been exhausted.
Since the CatHandle
closes a source handle, once it's done with it, it's possible for successive source handles to have the same native descriptor, if they were passed to .new as Cool or IO::Path objects.

role IO::Socket
From IO::Socket
(IO::Socket) method native-descriptor
method native-descriptor()
This returns a value that the operating system would understand as a "socket descriptor" and is suitable for passing to a native function that requires a socket descriptor as an argument such as setsockopt
.
class IO::Handle
From IO::Handle
(IO::Handle) method native-descriptor
Defined as:
method native-descriptor()
This returns a value that the operating system would understand as a "file descriptor" and is suitable for passing to a native function that requires a file descriptor as an argument such as fcntl
or ioctl
.
class IO::Socket::Async
From IO::Socket::Async
(IO::Socket::Async) method native-descriptor
method native-descriptor(--> Int)
Returns the file descriptor of this socket.
