Your second point depends, in fact, on whether buffer was allocated statically.

Er, no.

   #include <stdio.h>

   static char buffer[80];
   static char *bufferp=buffer;

   int main(int argc, char *argv[] )
   {
	char localbuffer[80];
	char *localbufferp=localbuffer;
	printf("buffer: %ld\n",sizeof buffer);
	printf("bufferp: %ld\n",sizeof bufferp);
	printf("localbuffer: %ld\n",sizeof localbuffer);
	printf("localbufferp: %ld\n",sizeof localbufferp);
   } 

Output:

   marcel@sarek[tmp]./a.out 
   buffer: 80
   bufferp: 8
   localbuffer: 80
   localbufferp: 8

As you can see, it depends entirely on whether you give sizeof the array or the pointer.
