iam getting error here
m_container = cont;
Error C3249 illegal statement or sub-expression for 'constexpr' function

sample code plz

how can i send response in multiple thread so that i can make my application more responsive

complete code is like

typedef struct
{
char *Domain;
char *Uri;
UINT32 IpAddr;
UINT32 Port;
int Direction; //0:-InBound,1:-Outbound
}PACKETINFO, *PPACKETINFO;

typedef int(CALLBACK *ProgressCallback)(PACKETINFO *info);

PPACKETINFO pinfo = { 0 };
const int ALLOW = 1;
const int BLOCK = 0;
Dowork(ProgressCallback funcaddr)
{



while(true)
{


if (!PacketsRecv(handle, packet, sizeof(packet), &packet_len, &addr))
{
fprintf(stderr, "warning: failed to read packet (%d)\n",
GetLastError());
continue;
}
//printf("Receiving packet....\n");
ParsePacket(packet, packet_len, &ip_header, NULL,
NULL, NULL, NULL, &tcp_header, NULL, &payload, &payload_len,
NULL, NULL);

if (ip_header == NULL || tcp_header == NULL || payload == NULL)
{
// Packet does not match the blacklist; simply reinject it.
if (!PacketSend(handle, packet, packet_len, NULL, &addr))
{
fprintf(stderr, "warning: failed to reinject packet (%d)\n",
GetLastError());
}
continue;
}

int response = 0;

if(funcaddr !=0 )
{
//callback send here
response = funcaddr(pinfo);

}

free(pinfo);
pinfo = NULL;

if (response == ALLOW )
{
// Packet does not match the blacklist; simply reinject it.
if (!PacketSend(handle, packet, packet_len, NULL, &addr))
{
fprintf(stderr, "warning: failed to reinject packet (%d)\n",
GetLastError());
}
continue;
}

else we block it by hijacking the
// connection.
}


}

currently iam facing the problem that user mode dll is continuously sending information to UI application which is making UI application crash, i want if we send response in different thread UI application will get more time to response to user mode dll

iam iterating on a neverending loop because this user mode dll is reading the packets send by driver application and analysis the packet and dropping the packets and re injecting according the response getting from UI application

actually this is a code of User mode dll which is getting information from driver, which it is sending it to UI and getting resonse from there, res is a response
pinfo is PACKETINFO which it is sending to UI

sir, as you can see the software(struct) is having intptr members which iam unable to convert into string values
