Generate core file with original process name

Question

I have a binary which will create multiple threads. Now when one of those threads crashes, I want the name of the core file generated to contain the original process name instead of the thread name.

When I use the %e specifier, it gives the thread name only (I think it is because in Linux, all threads are considered as LWPs).

How do I get the original process which created the thread in the core file name?

I looked at the man file, but it does not have any other specifier which I can use.

I get the thread name when I use %e. I want to get the executable name (the process which created the thread) – Glaciate

What thread name? Theads don't have names. Please provide an example. – Dungdungan

%E adds the path with the name of the executable. – Bats

Did you find a solution? I'm having the same problem. See https://mcmap.net/q/1559137/-core-dump-filename-gets-thread-name-instead-of-executable-name-with-core_pattern-e-p-core/564626 – Kaciekacy

@Kaciekacy Nope, I did not :( – Glaciate

See the other question (https://mcmap.net/q/1559137/-core-dump-filename-gets-thread-name-instead-of-executable-name-with-core_pattern-e-p-core/564626) for a workaround that I came up with. – Kaciekacy
