# GLibPollFD

#### Description [src]

    struct GPollFD {
      gint fd;
      gushort events;
      gushort revents;
    }

Represents a file descriptor, which events to poll for, and which events occurred.

###### Structure members

`fd`

  The file descriptor to poll (or a HANDLE on Win32).

`events`

  A bitwise combination from `GIOCondition`, specifying which events should be polled for. Typically for reading from a file descriptor you would use `G_IO_IN` | `G_IO_HUP` | `G_IO_ERR`, and for writing you would use `G_IO_OUT` | `G_IO_ERR`.

`revents`

  A bitwise combination of flags from `GIOCondition`, returned from the `poll()` function to indicate which events occurred.
