What is the status of DTrace substr function? It was integrated into Neveda
build 15 and it is available on Solaris 10 systems (U4 - u8 x64) I am working
on. I cannot find any documentation on it, and there appears to be a bug in
it that I cannot reproduced on OpenSolaris.
bash-3.00# more tst.d
#!/usr/sbin/dtrace
BEGIN
{
e = "/devices/pci-89789/jjjk";
seconds=5;
}
profile:::tick-1sec
{
printf("clause 1:string=%s\n", substr(e,0,9 )== "/devices/" ? "equal" :
"notequal")
}
profile:::tick-1sec
{
printf("clause 2:string=%s\n", substr(e,0,9 )== "/devices/" ? "equal" :
"notequal")
}
profile:::tick-1sec
{
seconds--;
}
profile:::tick-1sec
/ seconds < 1/
{
exit(0);
}
bash-3.00# dtrace -s./tst.d
dtrace: script './tst.d' matched 5 probes
