Like InputStream.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 glib.Bytes containing
the data that was read. This may be easier to use from language
bindings.
If count is zero, returns a zero-length glib.Bytes and does nothing. A
value of count larger than G_MAXSSIZE will cause a
G_IO_ERROR_INVALID_ARGUMENT error.
On success, a new glib.Bytes is returned. It is not an error if the
size of this object is not the same as the requested size, as it
can happen e.g. near the end of a file. A zero-length glib.Bytes is
returned on end of file (or if count is zero), but never
otherwise.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED 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 NULL is returned and error is set accordingly.
