Anti dll injection

Code:

---

void AntiInject ()
{
  HANDLE hProc = GetCurrentProcess();
  while (TRUE) {
      BlockAPI(hProc, "NTDLL.DLL", "LdrLoadDll");
      Sleep (100);
  }
}
 
BOOLEAN BlockAPI (HANDLE hProcess, CHAR *libName, CHAR *apiName)
{
  CHAR pRet[]={0xC3};
  HINSTANCE hLib = NULL;
  VOID *pAddr = NULL;
  BOOL bRet = FALSE;
  DWORD dwRet = 0;
 
  hLib = LoadLibrary (libName);
  if (hLib) {
      pAddr = (VOID*)GetProcAddress (hLib, apiName);
      if (pAddr) {
          if (WriteProcessMemory (hProcess,
                            (LPVOID)pAddr,
                            (LPVOID)pRet,
                            sizeof (pRet),
                            &dwRet )) {
              if (dwRet) {
                bRet = TRUE;
              }
          }
      }
      FreeLibrary (hLib);
  }
  return bRet;
}
