Subject: Perf Script Handler Arguments

Hi,
I am currently in the process of learning perfs python script support.
Is there a way to find out, without trial and error, how much parameter
a handler function has and what iformation the parameters are holding ?
The first 7 (event_name,context,common_cpu,common_secs,
common_nsecs,common_pid,common_comm ) are documented in the man-page and
are allways the same (?) but what is with the remaining ones ?
Syscalls__sys_enter_write for example needs 4 additional parameters:
unkown0, unkown1, unkown2 and bytesToWrite.
Regards
D.C.
