本文介绍了如何在FreeBSD中获取开放的posix共享内存段的列表的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在Linux中，我可以通过获取/dev/shm目录列表来获取已打开的posix共享内存段的列表.
In linux i can get list of opened posix shared memory segments by getting /dev/shm directory listing.
我如何以编程方式获取FreeBSD中所有打开的posix共享内存段的列表?假设使用shm_open打开了句段，而我甚至都不知道用作shm_open的第一个参数的名称的一部分.
How do i programmatically get list of all opened posix shared memory segments in FreeBSD?Assuming segments opened with shm_open and i don't know even a part of a name that was used as a first argument of shm_open.
推荐答案
您不能.请参阅/sys/kern/uipc_shm.c中的注释:
You can't. See the comment in /sys/kern/uipc_shm.c:
* TODO:
*
* (2) Need to export data to a userland tool via a sysctl. Should ipcs(1)
* and ipcrm(1) be expanded or should new tools to manage both POSIX
* kernel semaphores and POSIX shared memory be written?
*
* (3) Add support for this file type to fstat(1).
