C-bzero和memset的效率问题

Question

    memset(&seraddr, 0, sizeof(seraddr));
    //bzero(&seraddr, sizeof(seraddr));
    seraddr.sin_family = AF_INET;
    seraddr.sin_port = htons(SERVER_PORT);
    seraddr.sin_addr.s_addr = htonl(INADDR_ANY);

Answer 1

一样啦。想少敲几个按键就用 bzero 吧

Answer 2

These two functions have been historically been used in an interchangable manner, the reason being the nature of UNIX and its vastness. bzero() was originally a part of the BSD-Unix, and memset() was a part of the AT&T Unix. And later memset() was also adopted in the ANSI C and POSIX standards whereas bzero() was depracated. And while writing professional codes it is not advisable to use bzero() and longer, instead memset() should be used. (Although both will remain to be supported in the all the platforms).

用bzero()可以减少出错的几率，我就犯过将memset()将2,3参数搞反的错误。

Answer 3

一样的。只是memset能初始化为其他值。bzero是初始化为0。如果是初始化为0，bzero的语义更明确，而且更不容易出错。
