Calling mocked functions from a mock

Upon entering a mock function, the framework disables all mocking of the function being mocked. It is therefore possible to execute the function being mocked from within the mock function. Upon return from the mock, or if the mock executes another test, the mocking of that function is enabled again. An example (sample13) is shown below.2.1 

  void mock_printf(char *fmt, ...) {
    va_list args;
    static int count = 0;
    printf("*** printf called %d times *** \n", count++);
    va_start(args,fmt);
    vprintf(fmt, args);
    }

  void test_printf(void) {
    SIMULATE(invalid, TRUE);
    ALLOW_VALIDATE  ( printf, mock_printf);
    calculate(3,7,'+');
    }

If the mocked function is not present in the unit, calling it from a mock will simply call the default mock for that function.
