Coding style for parameterless functions

Coding style for parameterless functions

[Aktemur, Tankut Baris]

Hello,

I have a question regarding the coding style of parameterless
functions.  The internal document [1] gives an example where
they are written with the "void" keyword, like this:

  /* Declaration */
  static void foo (void);

  /* Definition */

  void
  foo (void)
  {
  }

I couldn't find the exact email, but I remember quite well that in a
discussion it was stated we should no longer use the void keyword
since we started coding in C++.

What's the current coding style that should be followed?

Also, the testsuite coding style document [2] explicitly states to write
"(void)".  But note that input programs in the testsuite are usually C
programs.

Regards
-Baris

Use () in C++ code.  "(void)" is a C-ism.

Yes, for C programs you have to do this.

thanks,
