Subject: static tracepoints - sdt.h vs. lttng

Hey all,
perf now has support for sdt.h static userland trace points, which is really
great. But I wonder, where can I find documentation on using it for custom
data types, like UTF16 strings, or custom structs? The Kernel seems to have
some custom API, can I leverage that also in userland?
The LTTNG-UST trace point API is much clearer in that regard:
http://lttng.org/man/3/lttng-ust/v2.7/
Which clearly supports arbitrary data types. But that is not supported by
perf, right?
How do other projects handle this?
Thanks
