And if you need to know the name of a process other than yourself, you can read the file /proc/<pid>/exefile, where <pid
> is the PID you are interested in.

Hi all,



Is there any way we can find the name of a process in QNX from the PID?
Or are there any APIs like getpid() for the process itself to know its name?



ProcessClass_t structure in the "sys/shutdown.h" header stores the process related information like PID and name.

While calling the shutdown_classify() callout during shutdown process, it provides the name of the process too: http://
www.qnx.com/developers/docs/7.0.0/index.html#com.qnx.doc.neutrino.lib_ref/topic/s/shutdown_system.html#
shutdown_system__shutdown_classify

But this structure is used only by the OS and there isn't any documentation of it.
