1 Here's a preliminary port of strace to FreeBSD.
3 Here are some notes about it :
5 - This couldn't have been done without the sources of the truss
6 utility by Sean Eric Fagan, which were of great help.
8 - The tracing mecanism used by FreeBD is a lot like the SVR4 one, so
9 this port shares a lot of code with the SVR4 port, including the
10 akward event loop when tracing multiple processes.
12 - This works for i386 binaries, although support for alpha processor
13 should be quite straight forward, but I do not have an alpha to
16 - Tracing linux binaries is not supported yet, but should be possible
19 - There are some issues with following forks, and only a few FreeBSD
20 specific syscalls are decoded right now.
22 - This was tested on FreeBSD 4.0. I believe the tracing interface is
23 present since at least FreeBSD 3.0, so it "should" work on all
24 latest releases. I have no idea for other BSDs, though.
