C++ (Cpp) safe_atolu Examples

Example #1

File: test-cap-list.c Project: arthur-c/systemd

/* verify cap_last_cap() against /proc/sys/kernel/cap_last_cap */
static void test_last_cap_file(void) {
        _cleanup_free_ char *content = NULL;
        unsigned long val = 0;
        int r;

        r = read_one_line_file("/proc/sys/kernel/cap_last_cap", &content);
        assert_se(r >= 0);

        r = safe_atolu(content, &val);
        assert_se(r >= 0);
        assert_se(val != 0);
        assert_se(val == cap_last_cap());
}

Example #2

File: parse-util.c Project: atulhjp/NetworkManager

int parse_pid(const char *s, pid_t* ret_pid) {
        unsigned long ul = 0;
        pid_t pid;
        int r;

        assert(s);
        assert(ret_pid);

        r = safe_atolu(s, &ul);
        if (r < 0)
                return r;

        pid = (pid_t) ul;

        if ((unsigned long) pid != ul)
                return -ERANGE;

        if (pid <= 0)
                return -ERANGE;

        *ret_pid = pid;
        return 0;
