Take a look at the gdk_input_add() function.

gint gdk_input_add	  (gint		     source,
			   GdkInputCondition condition,
			   GdkInputFunction  function,
			   gpointer	     data);

typedef enum
{
  GDK_INPUT_READ       = 1 << 0,
  GDK_INPUT_WRITE      = 1 << 1,
  GDK_INPUT_EXCEPTION  = 1 << 2
} GdkInputCondition;

This allows you to specify a function that will be called
any time a certain file descriptor becomes available for
reading or writing.
