[libvirt] [PATCHv2 1/2] openvz: convert popen to virCommand

[Matthias Bolte]

2010/12/7 Eric Blake <eblake at redhat.com>:
> popen must be matched with pclose (not fclose), or it will leak
> resources.  Furthermore, it is a lousy interface when it comes to
> signal handling.  We're much better off using our decent command
> wrapper.  Note that virCommand guarantees that VIR_FREE(outbuf) is
> both required and safe to call, whether virCommandRun succeeded or
> failed.

> Replace popen with virCommand usage.
