PollableInputStreamIF.isReadable

Checks if stream can be read. Note that some stream types may not be able to implement this 100% reliably, and it is possible that a call to g_input_stream_read() after this returns TRUE would still block. To guarantee non-blocking behavior, you should always use g_pollable_input_stream_read_nonblocking(), which will return a G_IO_ERROR_WOULD_BLOCK error rather than blocking. Since 2.28

Return Value

Type: int

TRUE if stream is readable, FALSE if not. If an error has occurred on stream, this will result in g_pollable_input_stream_is_readable() returning TRUE, and the next attempt to read will return the error.
