The functions in this section are used to establish

callbacks when some condition becomes true for

a file descriptor. They are currently just wrappers around

the <link linkend="glib-IO-Channels">IO Channel</link>
|

facility.

<!-- ##### 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.
|
|
|

<para>
|
|
Remove a callback added with gdk_input_add() or
|
|
gdk_input_add_full().
|
|
</para>
|
|
|
|
@tag: the tag returned when the callback was set up.
