    Question regarding library common resource

    Hello everyone,

    I have two apps which use a static library. In this library a common resource is referred. My question is how can I synchronize the access to this resource so they can be thread safe ? By using RMutex probably. But when my seconds process try to enter the critical section, KERN-EXEC 0 is thrown. How can I find the mutex already created ?

    Thanks

    Are you using RMutex::Create/OpenGlobal, and checking the result codes? Otherwise TFindMutex can check if a mutex exists or not, but it is easier to simply open it, and check if you get a KErrNotFound (or Create+KErrAlreadyExists).
