Performance between CYGWIN V1.3 V1.5
Hi, On CYGWIN V1.3, when I increase the process (Multi-Process) of the Application, the performance is comparably good when I have less process running. But when I moved the Application to CYGWIN V1.5, when I increase the process of the Application, the performance is bad when I have single process running. I am using the below Cygserver Settings: kern.srv.request_threads 50 kern.ipc.msgseg 2048 kern.ipc.msgssz 256 kern.ipc.msgmnb 65535 kern.ipc.msgtql 400 And the Semaphore and Shared memory Parameters are default. Can anyone suggest? Cheers, Neo. __ Sent from Yahoo!

Thanks immediate response.

You've just contradicted yourself. NOWAIT means non-blocking. If you want your program to block, waiting for messages, you don't set the NOWAIT option... you wait. That's what blocking means. If you do indeed want to do non-blocking, then EAGAIN is *absolutely normal*. It's supposed to do that. Get a book on Unix network programming, and take the problem up on a Unix network programming mailing list. This is not a Cygwin issue.

CYGWIN on win2k and win2k3.

Re: Smctl Method Returns Failure.
From my application : the calling semctl as follow:
method name()
{
int cntr=0
union semun semopts;
semopts.val=1
semctl ( *sid, cntr, SETVAL, semopts);
}
Am i calling the semctl in correct format? If so why am i getting the error?
If i look into sem.cc it is defined as follows:
semctl (int semid, int semnum, int cmd, ...)

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.

(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.

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.

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?
