/**
* SECTION: gcut-egg
* @title: External command (deprecated)
* @short_description: Convenience API for using external
* command. (deprecated)
*
* #GCutEgg encapsulates external command execution,
* communication and termination. #GCutEgg reports an error
* as #GError. It can be asserted easily by
* gcut_assert_error().
*
* External command is specified to constructor like
* gcut_egg_new(), gcut_egg_new_strings() and so
* on. External command isn't run at the
* time. gcut_egg_hatch() runs specified external command.
*
* Standard/Error outputs of external command are passed by
* #GCutEgg::output-received/#GCutEgg::error-received signals
* or #GIOChannel returned by
* gcut_egg_get_output()/gcut_egg_get_error().
* gcut_egg_write() writes a chunk to standard input of
* external command.
*
* To wait external command finished, gcut_egg_wait() can be
* used. It accepts timeout to avoid infinite waiting.
*
* e.g.:
* |[
* static GString *output_string;
* static GCutEgg *egg;
*
* void
* cut_setup (void)
* {
* output_string = g_string_new(NULL);
* egg = NULL;
* }
*
* void
* cut_teardown (void)
* {
* if (output_string)
* g_string_free(output_string, TRUE);
* if (egg)
* g_object_unref(egg);
* }
*
* static void
* cb_output_received (GCutEgg *egg, const gchar *chunk, gsize size,
* gpointer user_data)
* {
* g_string_append_len(output_string, chunk, size);
* }
*
* void
* test_echo (void)
* {
* GError *error = NULL;
*
* egg = gcut_egg_new("echo", "XXX", NULL);
* g_signal_connect(egg, "receive-output",
* G_CALLBACK(cb_output_received), NULL);
*
* gcut_egg_hatch(egg, &error);
* gcut_assert_error(error);
*
* gcut_egg_wait(egg, 1000, &error);
* gcut_assert_error(error);
* cut_assert_equal_string("XXX\n", output_string->str);
* }
* ]|
*
* Deprecated: 1.1.5: Use #GCutProcess instead.
