| fea681da | 34 | .SH DESCRIPTION |
| 63aa9df0 | 35 | .BR ipc () |
| efbfd7ec | 36 | is a common kernel entry point for the System\ V IPC calls |
| fea681da MK |
37 | for messages, semaphores, and shared memory. |
| 38 | .I call | |
| 39 | determines which IPC function to invoke; | |
| 40 | the other arguments are passed through to the appropriate call. | |
| 41 | .PP | |
| cf9c3958 | 42 | User-space programs should call the appropriate functions by their usual names. |
| fea681da | 43 | Only standard library implementors and kernel hackers need to know about |
| 63aa9df0 | 44 | .BR ipc (). |
| 47297adb | 45 | .SH CONFORMING TO |
| 60a90ecd | 46 | .BR ipc () |
| 8382f16d | 47 | is Linux-specific, and should not be used in programs |
| fea681da | 48 | intended to be portable. |
| d3989680 | 49 | .SH NOTES |
| b8d5a242 | 50 | On some architectures\(emfor example x86-64 and ARM\(emthere is no |
| d3989680 | 51 | .BR ipc () |
| 9d158688 | 52 | system call; instead, |
| d3989680 MK |
53 | .BR msgctl (2), |
| 54 | .BR semctl (2), | |
| 55 | .BR shmctl (2), | |
| 56 | and so on really are implemented as separate system calls. | |
