Equivalent to tempnam in C ++

Question

I need to create random names that I will use to create temporary files in a directory. I am currently using the C tempnam () function for this. My code is in C ++ and would like to use the C ++ equivalent to accomplish the same task. The code should work on both Solaris and Windows.

Does anyone know of such a thing in C ++? Any pointer to this would be greatly appreciated.

Answer 1

Try std::tempnamthe header cstdio.;)

The standard C library is still available in C ++ code. For convenience, they provide C ++ wrappers (in headers prefixed with "c" and without extension) and are available in the std namespace.

C (stdio.h tempnam , ++;))
