Method
GioPollableInputStreamcan_poll
Description
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.
For any given stream, the value returned by this method is constant; a stream cannot switch from pollable to non-pollable or vice versa.
