.SH NOTE
.PP
Some of the fields are immediately evaluated and remembered for performance reasons, so whenlog messages carry PIDs (not the default) this function needs to be reinvoked following \fBfork\fP (\fBclone\fP) in the respective children. When already linking with \fBlibpthread\fP, \fBpthread_atfork\fP callback registration could be useful.
