Error Creating Threads

I'm getting a fking error when creating a thread in the base:
Code:
BOOL APIENTRY DllMain( HMODULE hMod,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
//MessageBox(NULL, _T("DLL Injetada!"),_T("H4CK34D0"),MB_OK|MB_SYSTEMMODAL);
CreateThread(NULL, NULL, (LPTHREAD_START_ROUTINE)principal(), NULL, NULL, NULL);
DisableThreadLibraryCalls(hMod);
return true;
}

BOOL WINAPI principal() {
Sleep(9800);
try {
DWORD dllfile = (DWORD)GetModuleHandleA("CShell.dll");
if(dllfile == false) {
throw 1;
}
}
catch (int error) {
switch(error) {
case 1:
CreateThread(NULL, NULL, (LPTHREAD_START_ROUTINE)principal, NULL, NULL, NULL);
return false;
default:
//Unkown error!
return false;
}
}
CreateThread(NULL, NULL, (LPTHREAD_START_ROUTINE)princ, NULL, NULL, NULL);
return true;
}

On the first and last CreateThread it's giving: principal was not declared in this scope and princ was not declared in this scope.

Do you know the solution?
