semctl(2): data type for SEM_STAT_ANY

semctl(2): data type for SEM_STAT_ANY

[Martin Doucha]

Hello,
there's a minor error in the semctl(2) man page, the correct data type
for SEM_STAT_ANY return buffer is "struct semid_ds" because the kernel
code path is the same as for IPC_STAT and SEM_STAT:

https://github.com/torvalds/linux/blob/5ee88057889bbca5f5bb96031b62b3756b33e164/ipc/sem.c#L1789

The man page currently says that the data type for IPC_STAT and SEM_STAT
is "struct semid_ds" (correct) but then it says the data type for
SEM_STAT_ANY is "struct seminfo" (wrong).

Hello Martin,

This was fixed a few days ago.
Please, check commit 43ebbd192571b221b975c0d94bda3bcf0d633338.

Thanks,
