Subject: Let btrace(8) execute the END probe upon receiving a SIGTERM signal
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=7ba68130937bae642c32aa655a550ad8543990f1;p=openbsd

Let btrace(8) execute the END probe upon receiving a SIGTERM signal

While SIGINT (already handled) makes sense for interactive use, handling
SIGTERM in the same manner is less surprising for scripting.  This lets
you do:

  btrace ... & some workload; kill $!

and get the expected output.
