Hi all, I have proposed a set of IOCTLs on sndstat. The IOCTLs are nvlist-based, and the goal of these IOCTLs aims at eliminating text parsing as a generic user space API. Here is the link to the differential: https://reviews.freebsd.org/D26884. A piece of sample code is also provided to demonstrate the usage of the IOCTLs. Regards, Ka Ho
