## Functions

### cut_fork

    #define             cut_fork()

Makes child process.

e.g.:

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10

    int pid;
    pid = cut_fork();
    cut_assert_errno();

    if (pid == 0) {
      do_something_for_child_process();
      _exit(EXIT_SUCCESS);
    }

    do_something_for_parent_process();

#### Returns

Process ID.

Since: 0.8

### cut_wait_process()

    #define             cut_wait_process(pid, usec_timeout)

Waits a process specified by `pid` .

e.g.:

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11

    int pid;
    pid = cut_fork();
    cut_assert_errno();

    if (pid == 0) {
      do_something_for_child_process();
      _exit(EXIT_SUCCESS);
    }

    do_something_for_parent_process();
    cut_assert_equal_int(EXIT_SUCCESS, cut_wait_process(pid, 100));

#### Parameters

pid | Process ID to wait. |
usec_timeout | Timeout in usec. |

Since: 0.8

### cut_fork_get_stdout_message()

    #define             cut_fork_get_stdout_message(pid)

Reads a message from a process specified by `pid` .

e.g.:

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11

    int pid;
    pid = cut_fork();
    cut_assert_errno();

    if (pid == 0) {
      g_print("I'm a child.");
      _exit(EXIT_SUCCESS);
    }

    cut_assert_equal_string("I'm a child.", cut_fork_get_stdout_message(pid));
    cut_assert_equal_int(EXIT_SUCCESS, cut_wait_process(pid, 100));

#### Parameters

pid | Process ID. |

#### Returns

a message read from stdout of a process specified by `pid` .

Since: 0.8

### cut_fork_get_stderr_message()

    #define             cut_fork_get_stderr_message(pid)

Reads a message from a process specified by `pid` .

e.g.:

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10

    int pid;
    pid = cut_fork();
    cut_assert_errno();

    if (pid == 0) {
      g_print("I'm a child.");
      _exit(EXIT_SUCCESS);
    }

    cut_assert_equal_string("I'm a child.", cut_fork_get_stderr_message(pid));
