UnixInputStream

open class UnixInputStream(pointer: <Error class: unknown class><<Error class: unknown class>>) : InputStream, FileDescriptorBased, PollableInputStream

GUnixInputStream implements class@Gio.InputStream for reading from a UNIX file descriptor, including asynchronous operations. (If the file descriptor refers to a socket or pipe, this will use poll() to do asynchronous I/O. If it refers to a regular file, it will fall back to doing asynchronous I/O in another thread.)

Note that <gio/gunixinputstream.h> belongs to the UNIX-specific GIO interfaces, thus you have to use the gio-unix-2.0.pc pkg-config file or the GioUnix-2.0 GIR namespace when using it.

Constructors

Functions

canPoll

open fun canPoll(): Boolean

Checks if @stream is actually pollable. Some classes may implement #GPollableInputStream but have only certain instances of that class be pollable. If this method returns false, then the behavior of other #GPollableInputStream methods is undefined.

clearPending

open fun clearPending()

Clears the pending flag on @stream.

open fun close(cancellable: Cancellable? = null): <Error class: unknown class><Boolean>

Closes the stream, releasing resources related to it.

closeAsync

open fun closeAsync(ioPriority: <Error class: unknown class>, cancellable: Cancellable? = null, callback: AsyncReadyCallback?)

Requests an asynchronous closes of the stream, releasing resources related to it. When the operation is finished @callback will be called. You can then call g_input_stream_close_finish() to get the result of the operation.

closeFinish

open fun closeFinish(result: AsyncResult): <Error class: unknown class><Boolean>

Finishes closing a stream asynchronously, started from g_input_stream_close_async().

createSource

open fun createSource(cancellable: Cancellable? = null): <Error class: unknown class>

Creates a #GSource that triggers when @stream can be read, or

getFd

open fun getFd(): <Error class: unknown class>

Gets the underlying file descriptor.

hasPending

open fun hasPending(): Boolean

Checks if an input stream has pending actions.

isClosed

open fun isClosed(): Boolean

Checks if an input stream is closed.

isReadable

open fun isReadable(): Boolean

Checks if @stream can be read.

readBytes

open fun readBytes(count: <Error class: unknown class>, cancellable: Cancellable? = null): <Error class: unknown class><<Error class: unknown class>>

Like g_input_stream_read(), this tries to read @count bytes from the stream in a blocking fashion. However, rather than reading into a user-supplied buffer, this will create a new #GBytes containing the data that was read. This may be easier to use from language bindings.

readBytesAsync

open fun readBytesAsync(count: <Error class: unknown class>, ioPriority: <Error class: unknown class>, cancellable: Cancellable? = null, callback: AsyncReadyCallback?)

Request an asynchronous read of @count bytes from the stream into a new #GBytes. When the operation is finished @callback will be called. You can then call g_input_stream_read_bytes_finish() to get the result of the operation.

readBytesFinish

open fun readBytesFinish(result: AsyncResult): <Error class: unknown class><<Error class: unknown class>>

Finishes an asynchronous stream read-into-#GBytes operation.

readFinish

open fun readFinish(result: AsyncResult): <Error class: unknown class><Long>

Finishes an asynchronous stream read operation.

setPending

open fun setPending(): <Error class: unknown class><Boolean>

Sets @stream to have actions pending. If the pending flag is already set or @stream is closed, it will return false and set

skip

open fun skip(count: <Error class: unknown class>, cancellable: Cancellable? = null): <Error class: unknown class><Long>

Tries to skip @count bytes from the stream. Will block during the operation.

skipAsync

open fun skipAsync(count: <Error class: unknown class>, ioPriority: <Error class: unknown class>, cancellable: Cancellable? = null, callback: AsyncReadyCallback?)

Request an asynchronous skip of @count bytes from the stream. When the operation is finished @callback will be called. You can then call g_input_stream_skip_finish() to get the result of the operation.

skipFinish

open fun skipFinish(result: AsyncResult): <Error class: unknown class><Long>

Finishes a stream skip operation.
