select() fails with 10038 porting on 64 bit

[TdUser]

Hi

I'm currently trying to port my working application from 32 bit to 64 bit.
I see that the select() fails with error 10038. I did some research to find out the cause but
unable to drill it to the root cause. Im doubting it's to do with 32 and 64 bit models.
I tried to type cast based on some articles "converting from 32 bit to 64 bit " but no luck.
Any help is highly appreciated..... Thanks in advance

typedef struct {
SOCKET s;
Boolean Valid;
}Sock_Type, *Sock_Ptr_Type;

****************
Sock_Ptr_Type sockp;
fd_set rfds, wfds, efds;
struct timeval tv;
int n;
tv.tv_sec = 5;
tv.tv_usec = 0;
FD_ZERO(&rfds);
FD_ZERO(&wfds);
FD_ZERO(&efds);

for(int sockcnt=0;sockcnt<2;sockcnt++)
{
if(sockp[sockcnt].Valid)
{
FD_SET(sockp[sockcnt].s,&rfds);
FD_SET(sockp[sockcnt].s,&wfds);
FD_SET(sockp[sockcnt].s,&efds);
}
}

SOCKET temp = sockp[0].s;
n = select(temp+1,&rfds,&wfds,&efds,&tv);

Error from select(): 10038
An operation was attempted on something that is not a socket. The specified socket parameter refers to a file, not a socket.

Please use [code][/code] tags around your code to make it easier to read.

What type is "Boolean" in your Sock_Ptr_Type? It's not a standard type. It may be the problem if it is different widths in 64 v. 32bit environments.

Boolean is unsigned char

Boolean is unsigned char

Well, why is it not declared according to C++ standard as bool?
