TCPIP_DHCP_Enable（）成功的要求是什么？

对TCPIpH.DHCPYEnable（）的成功要求是什么？文档没有提供任何有关这方面的信息。当然，必须对DHCP模块进行初始化，例如作为TCPIPSYSTACKMODELYCONFIG的一部分，它用于TCPIPSISTACKILIALIALIZE（）。当然，我必须等待TrpIpPyStaskyStand（SysObj.TCPIp）= ySysStasuSueRead，否则我甚至无法获得调用TCPIpH.dHCPyEnable（）所需的TCPIPPNETURL句柄。但是，你还必须等待TCPIPSISTACKNESSUDP（NETH）=真吗？还有别的吗？或者，您应该重复调用TCPIpH.dHCPyEnable（），直到它成功吗？我已经看到在到达SysStasuSuxRead后直接调用TCPIpH.DHCPYEnable（）在某些情况下是失败的。等待FrTCPipStasknEnthPosif（）似乎有效，但这里的正确方法是什么？和声2.03b

    What are the requirements for TCPIP_DHCP_Enable() to succeed?

The documentation doesn't give any information about this. Of course the DHCP module must be initialized, for example as part of the TCPIP_STACK_MODULE_CONFIG which is used for TCPIP_STACK_Initialize(). And of course I have to wait for TCPIP_STACK_Status(sysObj.tcpip) == SYS_STATUS_READY, because otherwise I can't even get the TCPIP_NET_HANDLE, which you need for calling TCPIP_DHCP_Enable(). But do you also have to wait for TCPIP_STACK_NetIsUp(netH) == true? Or is there something else? Or should you just repeatedly call TCPIP_DHCP_Enable(), until it succeeds?

I have seen that calling TCPIP_DHCP_Enable() directly after reaching SYS_STATUS_READY is failing in some cases. With waiting for TCPIP_STACK_NetIsUp() it seems to work.

But what is the correct approach here?
