Class

GioMemoryInputStream

Description [src]

class Gio.MemoryInputStream : Gio.InputStream {
  parent_instance: GInputStream
}

GMemoryInputStream is a class for using arbitrary memory chunks as input for GIO streaming input operations.

As of GLib 2.34, GMemoryInputStream implements GPollableInputStream.

Ancestors

Constructors

g_memory_input_stream_new

Creates a new empty GMemoryInputStream.

g_memory_input_stream_new_from_bytes

Creates a new GMemoryInputStream with data from the given bytes.

Available since: 2.34

g_memory_input_stream_new_from_data

Creates a new GMemoryInputStream with data in memory of a given size.

Instance methods

g_memory_input_stream_add_bytes

Appends bytes to data that can be read from the input stream.

Available since: 2.34

g_memory_input_stream_add_data

Appends data to data that can be read from the input stream.

Methods inherited from GInputStream (19)
g_input_stream_clear_pending

Clears the pending flag on stream.

g_input_stream_close

Closes the stream, releasing resources related to it.

g_input_stream_close_async

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.

g_input_stream_close_finish

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

g_input_stream_has_pending

Checks if an input stream has pending actions.

g_input_stream_is_closed

Checks if an input stream is closed.

g_input_stream_read

Tries to read count bytes from the stream into the buffer starting at buffer. Will block during this read.

g_input_stream_read_all

Tries to read count bytes from the stream into the buffer starting at buffer. Will block during this read.

g_input_stream_read_all_async

Request an asynchronous read of count bytes from the stream into the buffer starting at buffer.

Available since: 2.44

g_input_stream_read_all_finish

Finishes an asynchronous stream read operation started with g_input_stream_read_all_async().

Available since: 2.44

g_input_stream_read_async

Request an asynchronous read of count bytes from the stream into the buffer starting at buffer. When the operation is finished callback will be called. You can then call g_input_stream_read_finish() to get the result of the operation.

g_input_stream_read_bytes

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.

Available since: 2.34

g_input_stream_read_bytes_async

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.

Available since: 2.34

g_input_stream_read_bytes_finish

Finishes an asynchronous stream read-into-GBytes operation.

Available since: 2.34

g_input_stream_read_finish

Finishes an asynchronous stream read operation.

g_input_stream_set_pending

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

g_input_stream_skip

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

g_input_stream_skip_async

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.

g_input_stream_skip_finish

Finishes a stream skip operation.

Methods inherited from GObject (43)
Methods inherited from GPollableInputStream (4)
g_pollable_input_stream_can_poll

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.

Available since: 2.28

g_pollable_input_stream_create_source

Creates a GSource that triggers when stream can be read, or cancellable is triggered or an error occurs. The callback on the source is of the GPollableSourceFunc type.

Available since: 2.28

g_pollable_input_stream_is_readable

Checks if stream can be read.

Available since: 2.28

g_pollable_input_stream_read_nonblocking

Attempts to read up to count bytes from stream into buffer, as with g_input_stream_read(). If stream is not currently readable, this will immediately return G_IO_ERROR_WOULD_BLOCK, and you can use g_pollable_input_stream_create_source() to create a GSource that will be triggered when stream is readable.

Methods inherited from GSeekable (5)
g_seekable_can_seek

Tests if the stream supports the GSeekableIface.

g_seekable_can_truncate

Tests if the length of the stream can be adjusted with g_seekable_truncate().

g_seekable_seek

Seeks in the stream by the given offset, modified by type.

g_seekable_tell

Tells the current position within the stream.

g_seekable_truncate

Sets the length of the stream to offset. If the stream was previously larger than offset, the extra data is discarded. If the stream was previously shorter than offset, it is extended with NUL (‘\0’) bytes.
