How to name a thread in Linux? (2)
This question already has an answer here:
I have a multithreaded Linux application written in C/C++. I have chosen names for my threads. To aid debugging, I would like these names to be visible in GDB, "top", etc. Is this possible, and if so how?
(There are plenty of reasons to know the thread name. Right now I want to know which thread is taking up 50% CPU (as reported by 'top'). And when debugging I often need to switch to a different thread - currently I have to do "
thread apply all bt" then look through pages of backtrace output to find the right thread).
The Windows solution is here; what's the Linux one?
This evidently won't compile, but it will give you an idea of where to go hunting. I'm not even sure its the right
PR_ command, but i think it is. It's been a while...
#include <sys/prctl.h> prctl(PR_SET_NAME,"<null> terminated string",0,0,0)
