Buffered input stream implements 'GI.Gio.Objects.FilterInputStream.FilterInputStream' and provides
for buffered reads.

By default, 'GI.Gio.Objects.BufferedInputStream.BufferedInputStream'\'s buffer size is set at 4 kilobytes.

To create a buffered input stream, use 'GI.Gio.Objects.BufferedInputStream.bufferedInputStreamNew',
or 'GI.Gio.Objects.BufferedInputStream.bufferedInputStreamNewSized' to specify the buffer\'s size at
construction.

To get the size of a buffer within a buffered input stream, use
'GI.Gio.Objects.BufferedInputStream.bufferedInputStreamGetBufferSize'. To change the size of a
buffered input stream\'s buffer, use
'GI.Gio.Objects.BufferedInputStream.bufferedInputStreamSetBufferSize'. Note that the buffer\'s size
cannot be reduced below the size of the data within the buffer.

Tries to read /@count@/ bytes from the stream into the buffer.
Will block during this read.

If /@count@/ is zero, returns zero and does nothing. A value of /@count@/
larger than @/G_MAXSSIZE/@ will cause a 'GI.Gio.Enums.IOErrorEnumInvalidArgument' error.

On success, the number of bytes read into the buffer is returned.
It is not an error if this is not the same as the requested size, as it
can happen e.g. near the end of a file. Zero is returned on end of file
(or if /@count@/ is zero),  but never otherwise.

If /@count@/ is -1 then the attempted read size is equal to the number of
bytes that are required to fill the buffer.

If /@cancellable@/ is not 'Nothing', then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error 'GI.Gio.Enums.IOErrorEnumCancelled' will be returned. If an
operation was partially finished when the operation was cancelled the
partial result will be returned, without an error.

On error -1 is returned and /@error@/ is set accordingly.

For the asynchronous, non-blocking, version of this function, see
'GI.Gio.Objects.BufferedInputStream.bufferedInputStreamFillAsync'.
