int getsockname(int sockfd, struct sockaddr *addr, socklen_t *addrlen); getsockname() returns the current address to which the socket sockfd is bound,in the buffer pointed to by addr. The addrlen argument should be initialized to indicate the amount
本文主要介绍了getsockname()和getpeername()的内核实现. 内核版本:3.6 Author:zhangskd @ csdn blog 应用层 int getsockname(int s, struct sockaddr *name, socklen_t *namelen); Get the current name for the specified socket. 获取本地套接口的名字,包括它的IP和端口. int getpeername(int s, struct so

原文:SQL去掉小数点有效数字后的所有0 第一种方法 select cast(2.5000000000000 as real) select cast(2 as real) select cast(2.00000 as real) 第二种方法 CREATE function [dbo].[ClearZero](@inValue varchar(50)) returns varchar(50) as begin declare @returnValue varchar(2
[字符串与数组] Q:Write an algorithm such that if an element in an MxN matrix is 0, its entire row and column is set to 0. 题目:写一个算法,如果一个 MxN矩阵中某个元素为0,则将该元素所在的行.列都置为0. 解答: 方法一:错误的解法,思维误区.依次遍历二维数组(矩阵),遇到一个0,就将这个0所在的行和列全部置为0,咋看一下没问题,仔细一想不对啊,这样做后,很有可能操作完后,这个二维数
Given a m x n matrix, if an element is 0, set its entire row and column to 0. Do it in-place. Example 1: Input: [ [1,1,1], [1,0,1], [1,1,1] ] Output: [ [1,0,1], [0,0,0], [1,0,1] ] Example 2: Input: [ [0,1,2,0], [3,4,5,2], [1,3,1,5]
