I was trying a trick from the advanced Dtrace presentation and ran
into a snag. Specifically, I was trying to do the trick called "Trick:
sizeof and profiling". It says this:
When used with profile provider, sizeof allows function profiling:
profile-1234hz
/arg0 >= `clock &&
arg0 <= `clock + sizeof (`clock)/
{
...
}
The thing is, I wanted to do the same thing with a user land function.
However, no matter what I did, I got an error about the function not
being defined. The function in question was in a shared library and
when I did a ustack, I got a symbol printed out. I tried the symbol as
printed by ustack (which included the version part of the library
name) and I tried it without the version, but neither worked.
What am I doing wrong? Or is it just not possible to do this for a
userland function?
