[dtrace-discuss] newbie question about syscall provider
I''d like to collect filenames for every ioctl syscall.
I found in manual that arg0-argN is arguments for system call
like that
ioctl
<http://src.opensolaris.org/source/s?refs=ioctl&project=/onnv>(*int*
fdes <http://src.opensolaris.org/source/s?defs=fdes&project=/onnv>,
*int* cmd
<http://src.opensolaris.org/source/s?defs=cmd&project=/onnv>,
intptr_t
<http://src.opensolaris.org/source/s?defs=intptr_t&project=/onnv>
arg <http://src.opensolaris.org/source/s?defs=arg&project=/onnv>)
ioctl(arg0,arg1,arg2)
i found that arg0 is file_t type, and try to trace pathname
dtrace -n ''syscall::ioctl:entry / execname != "dtrace" / {
printf("%s
%s",execname,arg0->f_vnode->v_path) }''
But i found that arg0 is not pointer at all. Now i complitly lost.

Hi,
try this:
dtrace -n ''syscall::ioctl:entry / execname != "dtrace" / {
printf("%s
%s\n",execname,fds[arg0].fi_pathname)}''
Thanks,
Gonzalo.
