ipcs output
 

Hello,
I am looking for an explanation of ipcs output.
Among the collumn,
key shmid owner perms bytes nattch status
I can only understand key, shmid, owner, perms, byte.
Where can I find the information about nattch and status?
Thank you

nattch is the number of currently attached processes, no idea about what status is precisely, Linux documentation is very poor on ipcs. Better to look at the source code.

I see, thank you. I will look into the source code in the future.
