Re: Difference Between CYGIPC And CYGServer
After goining through the code of shm.h and shm.c of Cygipc V1.09 that we are using, we have noticed that in function ShmCtl we have introduced logic to do the following: 1. Detach all PIDs from the passed Shared Memory Id. 2. Detach the PID of the process calling this function from all the shared memories present in the system. 3. Detach all dead PIDs from the passed Shared Memory Id, if they are left unattached before dying. 4. Detach all dead PIDs from all the Shared Memories persent in the system, if they are left unattached before dying. If we use Cygserver, can we achive these without making chages to cygserver code. Can we know whether the above mentioned points are covered in Cygserver? Thanks, Neo. ___ New Yahoo! Mail is the ultimate force in competitive emailing. Find out more at the Yahoo!

Re: Difference Between CYGIPC And CYGServer
All, After goining through the code of shm.h and shm.c of Cygipc V1.09 that we are using, we have noticed that in function ShmCtl we have introduced logic to do the following: 1. Detach all PIDs from the passed Shared Memory Id. 2. Detach the PID of the process calling this function from all the shared memories present in the system. 3. Detach all dead PIDs from the passed Shared Memory Id, if they are left unattached before dying. 4. Detach all dead PIDs from all the Shared Memories persent in the system, if they are left unattached before dying. If we use Cygserver, can we achive these without making chages to cygserver code. We would rather be comfortable changing our application code. Can we achieve these by calling Shmdt function from our application?

Re: Difference Between CYGIPC And CYGServer
When compiling we are getting the following error: apitest.c:28:31: ipc.h: No such file or directory apitest.c:29:31: shm.h: No such file or directory Since we were told not to include the Cygipc library when building the application, we have removed the cygipc library and sources from our work directory and Include path. As we have included the following header files and methods of Cygipc in our application we are getting errors when compiling. Header Files : ipc.h,sem.h,shm.h Calls : semctl, semget, semop shmtcl, shmget, shmat, shmdt msgctl, msgget, msgsnd, msgrcv Now that our intension is to use Cygserver, which are the corresponding header files and calls we need to include? I understand this is not going to be as simple as including the header files and building successfully.

Re: Difference Between CYGIPC And CYGServer
I have tried the suggested solution, but compilation failed as we have included the following calls to Cygipc: semctl, semget, semop shmtcl, shmget, shmat, shmdt msgctl, msgget, msgsnd, msgrcv and also included header files like ipc.h,sem.h,shm.h in our application If i have to sucessfully compile and run our application, what are the corresponding calls and header files that i have to include in our application to run with Cygserver.

Our programs are coded in C. Both provide (some) of the standard IPC calls. Both cygipc and cygserver implement the BSD interfaces for shared memory, semaphores, and message queues. (In cygwin-1.7.0+, cygserver will also implement POSIX-compliant shared memory objects and message queues). cygipc is practically unmaintained -- and the code quality is, er, less than ideal. cygserver is actively maintained and coded to a much higher standard. Since both, today, implement the same BSD-derived interface[see (4), below], to move from one to the other, you should simply (1) stop using -I/usr/include/cygipc in your build (1) stop using -lcygipc2 in your build (3) don't run ipc-daemon2.exe; instead, run /usr/bin/cygserver-config and follow the instructions. (4) remove calls to cygipc_set_err_handler cygipc_get_err_handler cygipc_set_debug cygipc_get_debug cygipc_tracing_enabled cygserver uses Win32 event logging for error and debug handling, so these hacks provided by cygipc are unnecessary. -- Chuck -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/ ___ Now you can scan emails quickly with a reading pane.

Difference Between CYGIPC And CYGServer
Hi, I have a few queries regarding cygserver and cygipc. what will be the impact to move from cygipc to cygserver? I have some systems programs which make calls to the CYGIPC, since these programs are coded long back. Can you please give us an idea of the things that need to be done to move from cygipc to cygserver. Our programs are coded in C. With Regards, Neo. ___ Inbox full of unwanted email?
