44 * Run a function in a subprocess and check the exit status and expected
45 * output (stdout and stderr combined) against the provided values. Expects
46 * the function to always exit (not die from a signal). data is optional data
47 * that's passed into the function as its only argument.
49 * This reports as three separate tests: whether the function exited rather
50 * than was killed, whether the exit status was correct, and whether the
53 typedef void (*test_function_type)(void *);
54 void is_function_output(test_function_type, void *data, int status,
55 const char *output, const char *format, ...)
56 __attribute__((__format__(printf, 5, 6), __nonnull__(1)));
59 * Run a setup program. Takes the program to run and its arguments as an argv
60 * vector, where argv[0] must be either the full path to the program or the
61 * program name if the PATH should be searched. If the program does not exit
62 * successfully, call bail, with the error message being the output from the
65 void run_setup(const char *const argv[]) __attribute__((__nonnull__));
68 * process_start starts a process in the background, returning an opaque data
69 * struct that can be used to stop the process later. The standard output and
70 * standard error of the process will be sent to a log file registered with
71 * diag_file_add, so its output will be properly interleaved with the test
74 * The process should create a PID file in the path given as the second
75 * argument when it's finished initialization.
77 * process_start_fakeroot is the same but starts the process under fakeroot.
78 * PATH_FAKEROOT must be defined (generally by Autoconf). If fakeroot is not
79 * found, process_start_fakeroot will call skip_all, so be sure to call this
80 * function before plan.
82 * process_stop can be called to explicitly stop the process. If it isn't
83 * called by the test program, it will be called automatically when the
86 struct process *process_start(const char *const argv[], const char *pidfile)
87 __attribute__((__nonnull__));
88 struct process *process_start_fakeroot(const char *const argv[],
90 __attribute__((__nonnull__));
91 void process_stop(struct process *);
