列出命名的信号量

Question

有没有办法列出所有posix-named-semaphores,ipcs似乎没有提供有关posix信号量的任何信息,例如ipcs -s输出是

------ Semaphore Arrays --------
key        semid      owner      perms      nsems     
0xcbc384f8 32769      xxx    600        1

虽然我创建了许多posix信号量,但列出`/ dev/shm'显示它们

-rw------- 1 xxx auniyal 16 2011-08-09 15:59 /dev/shm/sem.mysem
-rw------- 1 auniyal auniyal 16 2011-08-09 16:29 /dev/shm/sem.mysem1

Answer 1

所以现在解决方案似乎是列出/dev/shm例如

$ ls -al /dev/shm/sem.*|more
-rw------- 1 auniyal auniyal 16 2011-08-09 15:59 /dev/shm/sem.mysem
-rw------- 1 auniyal auniyal 16 2011-08-09 16:29 /dev/shm/sem.mysem1
-rw------- 1 auniyal auniyal 16 2011-08-09 16:37 /dev/shm/sem.mysem2
-rw------- 1 auniyal auniyal 16 2011-08-09 16:37 /dev/shm/sem.mysem3
-rw------- 1 auniyal auniyal 16 2011-08-09 16:39 /dev/shm/sem.mysem4
