Quoting Ivan Voras <ivoras@freebsd.org> (from Fri, 28 Nov 2008 15:59:23 +0100): > Can you document a bit more the construction of the probe: > > SDT_PROBE_DEFINE(foobar, source_file1, foo, entry); > SDT_PROBE_ARGTYPE(foobar, source_file1, foo, entry, 0, "int"); > SDT_PROBE_ARGTYPE(foobar, source_file1, foo, entry, 1, "const char *"); > SDT_PROBE_DEFINE(foobar, source_file1, foo, return); > SDT_PROBE_ARGTYPE(foobar, source_file1, foo, return, 0, "int"); > > What is the meaning of "source_file1" and "foo"? In case you reloaded the wiki page and it does not contain a reference to GEOM, reload it again. I added GEOM as an example how the module name could be constructed. BTW: Everyone is invited to improve the page.
