Scanning through sys/kern_clock.c it looks like getmicrotime is preferable to microtime since only getmicrotime accounts for tco_method (set via the kern.timecounter sysctl). The same is true with getnanotime vs nanotime, etc. However, I've noticed a good bit of kernel code is still calling microtime and nanotime rather than the get- versions: $ cd /usr/src/sys; grep -Rw microtime * | wc -l 85 $ cd /usr/src/sys; grep -Rw nanotime * | wc -l 12 $ cd /usr/src/sys; grep -Rw getmicrotime * | wc -l 39 $ cd /usr/src/sys; grep -Rw getnanotime * | wc -l 23 Is there are reason for code to still use the {micro,nano}time functions as opposed to get{micro,nano}time? I should point out that I am looking at a recently-supped 3.4 source tree. Although my friend cvsweb says that -current code is still calling {micro,nano}time also.
