Declaration 

gboolean
g_pollable_input_stream_can_poll (
  GPollableInputStream* stream
)

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.

Available since: 2.28

Return value

Type: gboolean

TRUE if stream is pollable, FALSE if not.
