Using stdio.h in a C++ program

[hanaa]

Hello..

Is it okay to use functions such as setvbuf (that is defined in stdio.h) in a C++ program?
I include stdio.h in the program and it works. Yet, I wonder if its okay.. stdio.h is a part of the standard C library and not standard C++ library, if I'm not wrong.
I also want to know if many such other functions can be used in C++ programming. Is there a clear line between the standard libraries for C and C++? Is using either in the other's programs a bad thing to do?

(I'm using GNU's DJGPP on Windows XP).

Thanks a ton. I love bytes.

Hanaa.

C functions are supposed to work in C++. Some functions can't be mixed, e.g. malloc/free and new/delete should be kept far from each other. C++ has more flexible functions/classes and methods. From a more purist point of view there is no need to use the functions available in stdio.h, C++ has its alternatives that can do what their C counterparts do and more.

kind regards,

setvbuf is mentioned in the c++ standard, and is expected to work as described in the C standard unless compiler/library itself has bugs.

Thank you..
1)Would you also tell me where I can find the Standards?

2) Would someone answer the others questions too, the questions in my first post here (if using C's functions in C++ programs in a bad idea).

I'm not sure about "finding standards", but generally, when working with C++, you can tell C and C++ apart by the header files. C++ doesn't use header files with a '.h', for example #include <stdio.h> is obviously a C standard ( because of the .h ), though obviously if you create a header file yourself, you'll use a '.h', but that's different.

In general, mixing C with C++ is frowned upon. It's just bad practice, though you will find those who do it.

Oh I didnt know the .h thing. Strange. I always wrote <iostream.h> in Turbo c++ version 3.0. Yeah , but in GCC, it accepts only <iostream>.

Hmmm. Okay. But I found nothing equivalent to setvbuf() (in stdio.h) in any other header file. Is there any, in a C++ header file?

Thank you.

#include <cstdio>

It, in turn, most likely incudes stdio.h
