常用示例
Example
ipcmk -M [segment_size_in_bytes]
Example
ipcmk -S [element_size]
Example
ipcmk -Q
Example
ipcmk -M [segment_size] -p [0644]
说明
ipcmk creates System V IPC (Inter-Process Communication) resources. These resources allow processes to communicate and synchronize: shared memory enables direct data sharing, semaphores coordinate access to resources, and message queues enable asynchronous messaging. Created resources are identified by a key and ID, which can be viewed with ipcs and removed with ipcrm. Resources persist until explicitly removed or system reboot.

- -S, --semaphore _COUNT_
- Create semaphore set with specified number of elements
- -Q, --queue
