- Reply-to: sourceware-bugzilla at sourceware dot org
Running the following script on a multi-threaded process yields traces only for
the tgid and not for any of the threads:
probe process(<path to multithreaded proc>).syscall
{
printf("%d thread[%d] syscall\n", pid(), tid())
}
output:
...
5739 thread[5739] syscall
5739 thread[5739] syscall
5739 thread[5739] syscall
5739 thread[5739] syscall
...
[ananth@thinktux]$ ls /proc/5739/task/
5739 5740 5741
