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
“output-received”/“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, "output-received", 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); }
