Currently, the dpdk log is out to stdout/stderr and syslog. We should support to output the log to another please, e.g. file or glog.Why not use rte_openlog_stream() / rte_log_get_stream() ? -- David Marchandrte_openlog_stream seems it could set an external FILE* stream. However, in the glog or C++ io stream, it's stream like std::cout. I think it's hard to use a FILE* stream to unify them. Use a custom logger function may be a better choice.
A FILE * stream can be created that uses any other function under the covers. See fopencookie(3)
