[previous] 3450 [next] Function '%s', with internal linkage, is being defined without a previous declaration.
Declarations and Definitions

A function with internal linkage is being defined without any previous declaration.

It is sometimes considered helpful to require that all functions which are defined in a file should be preceded by a prototype declaration at the top of the file. This avoids any possibility of the function being called before it has been declared. It is also helpful as a way of documenting function interfaces in one place at the start of the file.

For example: 


/*PRQA S 553,2017,3219 ++*/

static void foo(void)                   /* Message 3450 */
{
}
