C: ether_aton return type -

i wondering return type of ether_aton() function is?

from linux man page:

ether_aton() converts 48-bit ethernet host address asc standard hex-digits-and-colons notation binary data in network byte order , returns pointer in statically allocated buffer, subsequent calls overwrite. ether_aton() returns null if address invalid."

it mentioned in man page itself

struct ether_addr *ether_aton(const char *asc);
