linux c 连接超时。。。没有效果！哪儿的问题哦

上面的代码哪儿有问题吗？ 杂不行呢

[fenggui918]

unsigned long ulFin = 1; if (SOCKET_ERROR == ioctl(pSt_Client->hSocket, FIONBIO, (unsigned long*)&ulFin)) { return FALSE; } 连接前用0 试试

[jamon_tan]

unsigned long ulFin = 1; if (SOCKET_ERROR == ioctl(pSt_Client->hSocket, FIONBIO, (unsigned long*)&ulFin)) { return FALSE; } 第三个参数0表示阻塞，1表示非阻塞

你们在说什么？

[renwotao2009]

是select超时吗？如果是select返回0则为超时情况

0x00005421 FIONBIO const int * 不是long *

[nswcfd]

sorry，使用long int *好像也没有什么问题（在小端机器上），请忽略#5楼的内容。
