Thread32First returning bogus thread id - c++

Question

Thread32First returns true so I know the function isn't failing. However, it keeps returning the same value for the th32ThreadID data member of THREADENTRY32, 0. Doesn't matter what process I try it on, it continues to be the same thread id: 0.
Here's my code:
#include <windows.h>
#include <tlhelp32.h>
#include <stdio.h>
BOOL EnableDebugPriv(HANDLE proc);
int main()
{
HANDLE hSnapshot;
HANDLE hThread;
THREADENTRY32 thread32;
DWORD dwPid = 15404;
EnableDebugPriv(OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwPid));
hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPTHREAD, dwPid);
if(hSnapshot == INVALID_HANDLE_VALUE)
{
printf("Error getting snapshot: %lu\n", GetLastError());
return 1;
}
thread32.dwSize = sizeof(THREADENTRY32);
if(!Thread32First(hSnapshot, &thread32))
{
printf("Error thread32first\n");
return 1;
}
printf("Thread Id: %lu\n", thread32.th32ThreadID);
hThread = OpenThread(THREAD_ALL_ACCESS, FALSE, thread32.th32ThreadID);
if(hThread == NULL)
{
printf("Error getting handle: %lu\n", GetLastError());
return 1;
}
return 0;
}
BOOL EnableDebugPriv(HANDLE proc)
{
HANDLE hToken;
LUID sedebugnameValue;
TOKEN_PRIVILEGES tkp;
// pass our opened process handle
OpenProcessToken(proc, TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken);
LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &sedebugnameValue);
tkp.PrivilegeCount = 1;
tkp.Privileges[0].Luid = sedebugnameValue;
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
if(AdjustTokenPrivileges(hToken, FALSE, &tkp, sizeof tkp, NULL, NULL))
{
CloseHandle(hToken);
return TRUE;
}
else
{
MessageBox(NULL,"Bro, you gotta be an admin to set privs like this", "Shit", MB_OK);
CloseHandle(hToken);
return FALSE;
}
}
Note: I am aware that using a static process ID like I am could cause problems. However, I make sure the process is still running with the same process ID. That's not the problem.
