Virtual Method

GioPollableInputStreamis_readable

since: 2.28

Declaration [src]

gboolean
is_readable (
  GPollableInputStream* stream
)

Description [src]

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.

The behaviour of this method is undefined if g_pollable_input_stream_can_poll() returns FALSE for stream.

Available since: 2.28

Return value

Type: gboolean

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.
