Unnamed Arguments in Function Definitions

(ISO C, §6.9.1) The C compiler can accept unnamed arguments in a function definition.

  void f(int ) {} /* OK if ANSI strict checking is disabled */ 


  void f(int i) {} /* ALWAYS OK */

The compiler allows this extension if ANSI strict checking is disabled:

• In the IDE, use the C/C++ Language Settings panel's ANSI Strict setting
• On the command line, use the compiler's -ansi strict option
• In source code, use #pragma ANSI_strict
