Have a look at the ToolHelp functions Thread32First & Thread32Next,
and GetExitCodeThread.

here's the copy and paste:

#include <stdio.h>
#include <psapi.h>
#include <time.h>

void PrintProcessNameAndID(DWORD processID) {

char szProcessName[MAX_PATH + 1] = "unknown";

if ( (hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ,
FALSE, processID)) != NULL ) {

if ( EnumProcessModules(hProcess, &hMod, sizeof(HMODULE),
&cbNeeded)) {
GetModuleBaseName(hProcess, hMod, szProcessName,
sizeof(szProcessName));
}
printf( "%s (Process ID: %u)\n", szProcessName, processID );
CloseHandle(hProcess);
}
}


void PrintModules( DWORD processID )
{
HMODULE hMods[1024];
HANDLE hProcess;
DWORD cbNeeded;
unsigned int i;

// Print the process identifier.

printf( "\nProcess ID: %u\n", processID );

// Get a list of all the modules in this process.

hProcess = OpenProcess( PROCESS_QUERY_INFORMATION |
PROCESS_VM_READ,

if( EnumProcessModules(hProcess, hMods, sizeof(hMods), &cbNeeded))
{
for ( i = 0; i < (cbNeeded / sizeof(HMODULE)); i++ )
{
char szModName[MAX_PATH];

// Get the full path to the module's file.

if ( GetModuleFileNameEx( hProcess, hMods[i], szModName,
sizeof(szModName)))
{
// Print the module name and handle value.

printf("\t%s (0x%08X)\n", szModName, hMods[i] );
}
}
}

CloseHandle( hProcess );
}

// Print the process identifier.

printf( "\nProcess ID: %u\n", processID );

// Print information about the memory usage of the process.

hProcess = OpenProcess( PROCESS_QUERY_INFORMATION |

}

}
}

Sleep(1000 * 1000);

return 0;
}
