linux网络编程之socket（十二） select函数的并发限制和poll函数应用举例

启动select 的服务器端程序，再启动客户端测试程序：

simba@ubuntu:~/Documents/code/linux_programming/UNP/socket$ ./echoser_select

......................................................................

count = 1015

recv connect ip=127.0.0.1 port=51299

count = 1016

recv connect ip=127.0.0.1 port=51300

count = 1017

recv connect ip=127.0.0.1 port=51301

count = 1018

recv connect ip=127.0.0.1 port=51302

count = 1019

recv connect ip=127.0.0.1 port=51303

count = 1020

recv connect ip=127.0.0.1 port=51304

accept error: Too many open files

simba@ubuntu:~/Documents/code/linux_programming/UNP/socket$ ./conntest

...................................................................................................

count = 1015
