I just need to print the file descriptor number as a string. I would like to join fd and file name into one string and then aggregate on reads/writes reason I want to do this is, for sockets fi_pathname just shows up as "unknown" - instead if I can get fd, I can do pfiles and get the socket details ..

If you are trying to print the name of the file from the FD them you can use the fds[] array. Something like syscall::read:entry /pid == $1 / { printf("Reading (%s) \n", fds[arg0].fi_pathname); } -Angelo On Aug 18, 2009, at 4:27 PM, venkateshu.cherukupa...@ubs.com wrote: > > Hi, > > I am trying to convert and print fd from read/write calls into string > and it fails with below error. > > dtrace: error on enabled probe ID 1 (ID 23: syscall::read:entry): > invalid address (0x0) in action #1 > > What am I missing ? > > syscall::read:entry > /pid == $1 / > { > printf("Reading FD (%s) \n", (string)arg0); > > } > > Printing fd as integer (%d) works ok. > > Cheers, > Venkat > Visit our website at http://www.ubs.com > > This message contains confidential information and is intended only > for the individual named.
