Hi, Can I access the details of a semid_ds data structure from a kernal module, for the process "current". I just want to see the contents of this buffer corresponding to the process. I have seen that in the task_struct there is pointer to the sem_undo. But nothing related to the semid_ds. If no such link exists from the task_struct, how can the process maintain all the semaphores used by it? -- With regards, Jagadeesh Bhaskar P R&D Engineer HCL Infosystems Ltd Pondicherry -- Kernelnewbies: Help each other learn about the Linux kernel.
