我正在使用线程在 server.threading 上发布数据。线程工作正常,数据正在服务器上接收,但每次我收到每个请求的分段错误/核心转储异常。
我的线程函数
void* APR_THREAD_FUNC thread_init(apr_thread_t *thd,void *data)
{
DATA_INFO_SOCK *dt=(DATA_INFO_SOCK*)data;
apr_status_t result;
result=apr_socket_sendto(dt->new_sock,dt->addr,0,dt->payload,dt->len);
if(result==APR_SUCCESS)
{
result=apr_socket_recvfrom(dt->addr,dt->new_sock,0,dt->resp,dt->rec_len);
}
result=apr_socket_close(dt->new_sock);
apr_thread_exit(thd, APR_SUCCESS);
}
我的线程启动 C 代码

apr_status_t result;
