### Virtual Method

# Gio PollableInputStreamis_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.
