That tells you that it's a Lisp function that's
"built-in", meaning that it's implemented in C.
And it points you to the C definition in fns.c.
That C code provides the complete definition,
including the doc string.
> DEFUN ("mapc", Fmapc, Smapc, 2, 2, 0,
That tells you that Lisp function `mapc' is
defined using C definition Fmapc, and the
function takes two arguments. Someone else
can provide or point you to more info about
this.
