The original code incorrectly used the stdout null check condition
for both stdout and stderr pointer selection. This caused incorrect
behavior when stderr is null but stdout is not, or vice-versa.
This fix separates the null checks for stdout and stderr into
independent conditions, ensuring each stream is properly selected
based on its own null status.
