void function - return value

[maggmich]

Hello!

Why shouldn't I implement a return-value f. ex. "return(0)" into a void function?
I heard this once in terms of tidy programming.
f. i.:

void writeString(char *str)
{
  printf("%s",str);
  // return(0); ?????? I shouldn't! Why?
}

Yours
Jürgen

The way you return from a void function is simply by doing

void writeString(char *str)
{
    printf("%s",str);
    return;
}

Because it would be wrong and misleading. A function with a void return value does not return 0; it returns nothing.
