title: Does it prohibited calling classic C function from Objective-C++ class method body?
body: <p>I have experienced some strange behavior of Objective-C++.
  I have an Objective-C++ class, and it calls a classic C function in a method body.
  But linker cannot find the C function.</p>
  
  <p>I described the problem here:
  <a href="https://stackoverflow.com/questions/2213589/xcode-print-symbol-not-found-for-my-c-function-which-used-in-objective-c-method-b/2213671#2213671">Xcode print symbol not found for my C function which used in Objective-C method body</a></p>
  
  <p>I solved the problem by changing Objective-C++ class to Objective-C class, but the question is still remained. Does it prohibited calling C function in Objective-C++ class?</p>
