-<!-- ##### ENUM GdkInputCondition ##### -->
-<para>
-A set of bit flags used to specify conditions for which
-an input callback will be triggered. The three members
-of this enumeration correspond to the @readfds,
-@writefds, and @exceptfds arguments to the
-<function>select</function> system call.
-</para>
-
-@GDK_INPUT_READ: the file descriptor has become available for reading.
-(Or, as is standard in Unix, a socket or pipe was closed
-at the other end; this is the case if a subsequent read
-on the file descriptor returns a count of zero.)
-@GDK_INPUT_WRITE: the file descriptor has become available for writing.
-@GDK_INPUT_EXCEPTION: an exception was raised on the file descriptor.
-
-<!-- ##### USER_FUNCTION GdkInputFunction ##### -->
-<para>
-A callback function that will be called when some condition
-occurs.
-</para>
-
-@data: the user data passed to gdk_input_add() or gdk_input_add_full().
-@source: the source where the condition occurred.
-@condition: the triggering condition.

-gdk_input_add_full().

-@tag: the tag returned when the callback was set up.
