Hello.
I'm new to Linux (mostly a Win32 developer). I am porting some code that
uses the Win32 CreateMutex in order to synchronize access to a file across
several processes. On Win32, a mutex works across processes (not only
threads). I remember a class I took years ago allowed file locking as a
method to sync up processes, but this method uses the file handle
(descriptor) from calls like _open to lock on. I'm use C++ ofstream which
doesn't allow access to the actual file handle (anymore).
Using C or C++, how to I synchronize two processes? I looked at
pthread_mutex_xxxx, but this is for threads. Do I use a semaphore? Seems
like overkill; I just need a binary yes or no lock.
BTW, I'm using RedHat 6.1.
Thanks for the help.
