Yes. Below is a snippet from the semctl(2) manpage on a Linux machine:
| SEM_STAT (Linux specific)
| Returns a semid_ds structure as for IPC_STAT. However, the
| semid argument is not a semaphore identifier, but instead
| an index into the kernel's internal array that maintains
| information about all semaphore sets on the system.
