Problem during compile (iostream.h error)

[JoJo]

Hi,

i working on a small project to learn again how to make some stuff in C. I use Borland C++ 5.01. Ok at the moment i try to make a new dll file (the second one) and i want to put a nice search function (found on planet-source code) into this dll. I made already a dll and it seems that it works but now it seems that my Borland doesn´t like me or my code...here my source code of my second dll. I can not compile this source code with included iostream.h. If i include this iostream (i must do it, cause i need it for the search function) the Borland compiler gives me this error message:

error: IOSTREAM.H(24,2):Error directive: Must use C++ for the type iostream.

What should i change to compile this source code ?
