C++ (Cpp) object::is_none Examples

Example #1

File: Exception.cpp Project: 18768108070/pyv8

void CJavascriptException::PrintCallStack(py::object file)
{
  CPythonGIL python_gil;

  PyObject *out = file.is_none() ? ::PySys_GetObject((char *) "stdout") : file.ptr();

  int fd = ::PyObject_AsFileDescriptor(out);

  Message()->PrintCurrentStackTrace(m_isolate, fdopen(fd, "w+"));
}
