final class NIOFileHandleDeprecated. NIOFileHandle is a handle to an open file descriptor.
@frozen struct BoolA value type whose instances are either true or false.
convenience init(_deprecatedPath path: String) throws Open a new NIOFileHandle. This operation is blocking.
convenience init(_deprecatedPath path: String, mode: NIOFileHandle.Mode = .read, flags: NIOFileHandle.Flags = .default) throws Open a new NIOFileHandle. This operation is blocking.
init(_deprecatedTakingOwnershipOfDescriptor descriptor: CInt) Create a NIOFileHandle taking ownership of descriptor. You must call NIOFileHandle.close or NIOFileHandle.takeDescriptorOwnership before this object can be safely released.
var description: String { get }func close() throws func duplicate() throws -> NIOFileHandle Duplicates this NIOFileHandle. This means that a new NIOFileHandle object with a new underlying file descriptor is returned. The caller takes ownership of the returned NIOFileHandle and is responsible for closing it.
func takeDescriptorOwnership() throws -> CInt Take the ownership of the underlying file descriptor. This is similar to close() but the underlying file descriptor remains open. The caller is responsible for closing the file descriptor by some other means.
func withUnsafeFileDescriptor<T>(_ body: (CInt) throws -> T) throws -> T struct FlagsFlags allows to specify additional flags to Mode, such as permission for file creation.
struct ModeMode represents file access modes.
convenience init(descriptor: CInt) Create a NIOFileHandle taking ownership of descriptor. You must call NIOFileHandle.close or NIOFileHandle.takeDescriptorOwnership before this object can be safely released.
convenience init(path: String) throws Open a new NIOFileHandle. This operation is blocking.
convenience init(path: String, mode: NIOFileHandle.Mode = .read, flags: NIOFileHandle.Flags = .default) throws Open a new NIOFileHandle. This operation is blocking.
