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>

A set of bit flags used to specify conditions for which

@writefds, and @exceptfds arguments to the

<function>select</function> system call.
