Class
GioMemoryInputStream
Description [src]
class Gio.MemoryInputStream : Gio.InputStream
implements Gio.PollableInputStream, Gio.Seekable {
/* No available fields */
}GMemoryInputStream is a class for using arbitrary
memory chunks as input for GIO streaming input operations.
As of GLib 2.34, GMemoryInputStream implements
GPollableInputStream.
Constructors
g_memory_input_stream_new_from_bytes
Creates a new GMemoryInputStream with data from the given bytes.
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.
since: 2.34
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.
since: 2.44
g_input_stream_read_all_finish
Finishes an asynchronous stream read operation started with
g_input_stream_read_all_async().
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.
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.
since: 2.34
g_input_stream_read_bytes_finish
Finishes an asynchronous stream read-into-GBytes operation.
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 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.
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.
since: 2.28
g_pollable_input_stream_is_readable
Checks if stream can be read.
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.
Signals
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
