SO_REUSEADDR on Solaris

唉，还是 SO_REUSEADDR ....\r\n\r\n我希望构造两个socket，绑定到同一个本地端口。一个监听、一个对外连接。\r\n似乎这是用SO_REUSEADDR可以解决的，可是在我的Solaris 9就是不允许。\r\n\r\n同样的代码在Windows和Linux下都试过，达到了我的目的。难道Solaris \r\n不允许这样的行为？\r\n\r\n代码：----------------------------------------------------\r\n#include \"stdafx.h\"\r\n#include <winsock2.h>;\r\n\r\nint sock_init()\r\n{\r\n WORD wVersionRequested;\r\n WSADATA wsaData;\r\n int err;\r\n\r\n wVersionRequested = MAKEWORD( 2, 2 );\r\n\r\n err = WSAStartup( wVersionRequested, &wsaData );\r\n if ( err != 0 ) {\r\n  return 0;\r\n }\r\n return 0;\r\n}\r\n\r\nint _tmain(int argc, _TCHAR* argv[])\r\n{\r\n sock_init();\r\n SOCKET  lhdl, chdl;\r\n sockaddr_in laddr;\r\n\r\n BOOL one = TRUE;\r\n\r\n laddr.sin_family = AF_INET;\r\n laddr.sin_port   = htons(5150);\r\n laddr.sin_addr.s_addr = htonl(INADDR_ANY);\r\n\r\n lhdl = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);\r\n chdl = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);\r\n\r\n bind(lhdl, (SOCKADDR*)&laddr, sizeof(laddr));\r\n\r\n//++++++++++++++++++++++++++++++++++++++++++++++++\r\n// if we uncomment the setsockopt call, second bind will success\r\n//++++++++++++++++++++++++++++++++++++++++++++++++\r\n// setsockopt(chdl, SOL_SOCKET, SO_REUSEADDR, (const char*)&one,sizeof one);\r\n bind(chdl, (SOCKADDR*)&laddr, sizeof(laddr));\r\n\r\n listen(lhdl, 5);\r\n\r\n SOCKADDR_IN raddr;\r\n raddr.sin_family = AF_INET;\r\n raddr.sin_port   = htons(80);\r\n raddr.sin_addr.s_addr = inet_addr(\"202.38.215.238\";\r\n\r\n connect(chdl, (SOCKADDR*)&raddr, sizeof(raddr));\r\n\r\n // wait for checking port status via netstat\r\n getchar();\r\n WSACleanup();\r\n\r\n return 0;\r\n}
