Using the –toption to specify the thread, you can get the information specific to a thread without stopping the other threads as shown below.

Example 8 Printing the output for a sample threaded process with the -t option

-------------------------------- lwpid : 119942 -------------------------------

0:60000000c042fb70 : __pause_sys() + 0x30 (/usr/lib/hpux32/libc.so.1)

A special argument -1enables you to trace the calling process without entering the PID of the process. Hence, you can skip the process of finding the PID by using this argument on a calling process.

The example below shows the usage of special argument -1that can be used to run pstack on the calling process. In this case, the calling process is the shell itself.
