C: ether_aton 返回类型

Question

我想知道 ether_aton() 函数的返回类型是什么？

来自 Linux 手册页:

ether_aton() converts the 48-bit Ethernet host address asc from the standard hex-digits-and-colons notation into binary data in network byte order and returns a pointer to it in a statically allocated buffer, which subsequent calls will overwrite. ether_aton() returns NULL if the address is invalid."

Answer 1

man page中提到本身

struct ether_addr *ether_aton(const char *asc);
