[libvirt] [PATCH] util: remove some no-op thread functions
Posted by Daniel P. Berrangé 4 years, 7 months ago
Neither virThreadInitialize or virThreadOnExit do anything since we
dropped the Win32 threads impl, in favour of win-pthreads.

Nit: this is the resulting code



     case DLL_THREAD_ATTACH:
         /* Nothing todo in libvirt yet */
         break;

     case DLL_THREAD_DETACH:
         /* Nothing todo in libvirt yet */
         break;


You can spare a few lines here:

     case DLL_THREAD_ATTACH:
     case DLL_THREAD_DETACH:
         /* Nothing todo in libvirt yet */
         break;
