Not sure what you mean by FD as a string. 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);
}

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
