Note, that this would be this according to our style guide:
int
function(void)
{
}

C only puts out that warning if you define a global symbol that will be
exported to other files. If you are only needing these symbols locally,
you should state so by adding a "static" before the definition, and the
warning will disappear:
static int
function(void)
{
}
