1604 * @test_trap_flags: Flags to modify forking behaviour.
1606 * Fork the current test program to execute a test case that might
1607 * not return or that might abort. The forked test case is aborted
1608 * and considered failing if its run time exceeds @usec_timeout.
1610 * The forking behavior can be configured with the #GTestTrapFlags flags.
1612 * In the following example, the test code forks, the forked child
1613 * process produces some sample output and exits successfully.
1614 * The forking parent process then asserts successful child program
1615 * termination and validates child program outputs.
1619 * test_fork_patterns (void)
1621 * if (g_test_trap_fork (0, G_TEST_TRAP_SILENCE_STDOUT | G_TEST_TRAP_SILENCE_STDERR))
1623 * g_print ("some stdout text: somagic17\n");
1624 * g_printerr ("some stderr text: semagic43\n");
1625 * exit (0); /* successful test run */
1627 * g_test_trap_assert_passed();
1628 * g_test_trap_assert_stdout ("*somagic17*");
1629 * g_test_trap_assert_stderr ("*semagic43*");
1633 * This function is implemented only on Unix platforms.
1635 * Returns: %TRUE for the forked child and %FALSE for the executing parent process.
