| LD_PRELOAD the VCL |
| ================== |
| |
| vcl-ldpreload is a LD_PRELOAD library that uses the VPP Communications Library (VCL). |
| |
| User can LD_PRELOAD any application that uses POSIX socket API. |
| |
| NOTE: The sources have been moved to ``vpp/src/vcl`` and ``libvcl_ldpreload.so`` is built with VPP and can be found in |
| ``vpp/build-root/install-vpp[_debug]-native/vpp/lib`` |
