Openthread SRP Client in main.c - openthread

Question

Hello I'm trying to start the SRP(Service Registration Protocol) Client in my main.c. I've found following description in openthread/srp_client.h"
* This function starts the SRP client operation.
SRP client will prepare and send "SRP Update" message to the SRP server once all the following
conditions are met:
- The SRP client is started - `otSrpClientStart()` is called.
- Host name is set - `otSrpClientSetHostName()` is called.
- At least one host IPv6 address is set - `otSrpClientSetHostName()` is called.
- At least one service is added - `otSrpClientAddService()` is called.
It does not matter in which order these functions are called. When all conditions are met, the
SRP client will wait for a short delay before preparing an "SRP Update" message and sending to
server.
* #param[in] aInstance A pointer to the OpenThread instance.
* #param[in] aServerSockAddr The socket address (IPv6 address and port number) of the SRP
* server.
*
* #retval OT_ERROR_NONE SRP client operation started successfully or it is already
running with same server
* socket address and callback.
* #retval OT_ERROR_BUSY SRP client is busy running with a different socket address.
* #retval OT_ERROR_FAILED Failed to open/connect the client's UDP socket.

otError otSrpClientStart(otInstance *aInstance, const otSockAddr *aServerSockAddr);
srp_client.h
otError otSrpClientStart(otInstance *aInstance, const otSockAddr *aServerSockAddr)
otError otSrpClientSetHostName(otInstance *aInstance, const char *aName)
otError otSrpClientAddService(otInstance *aInstance, otSrpClientService *aService)
My Main.c
#include <openthread/srp_client.h>
static void SrpClientInit(void){
otSrpClientStart(**What comes in here?**, **How can i Use the EUI64 as IP?**)
otSrpClientSetHostName(**What comes in here?**, 'SrpTest')
otSrpClientAddService(**What comes in here?**,**What comes in here?**)
}
int main(int argc, char *argv[]){
....
SrpClientInit();
....
}
Can Someone explain me how i can define the parameters for the function?

This is my Code and I can Flash the Firmware but the Thread Device doesn't connect to the Thread Network anymore.
void SrpClientInit(void)
{
otSockAddr SRP_1;
SRP_1.mAddress.mFields.mComponents.mIid.mFields.m8[0] = 0xff;
SRP_1.mPort = 0xff;
otSockAddr *SRP_1_pointer = &SRP_1;
otIp6Address SRPaddr;
SRPaddr.mFields.m16[0] = 0xfff;
otIp6Address *SRPaddr_pointer = &SRPaddr;
otSrpClientService SRPclient;
SRPclient.mName = "_knx._udp";
SRPclient.mInstanceName = "fancy-service";
//SRPclient.mTxtEntries->mKey = NULL;
SRPclient.mPort = 12356;
SRPclient.mPriority = 1;
SRPclient.mWeight = 1;
SRPclient.mNumTxtEntries = 1;
otSrpClientService *SRPclient_pointer = &SRPclient;
otSrpClientSetHostName(sInstance, "SRPtest");
otSrpClientSetHostAddresses(sInstance,SRPaddr_pointer,0x0f);
otSrpClientAddService(sInstance, SRPclient_pointer);
otSrpClientStart(sInstance,SRP_1_pointer);
}
