You can do this using named mutex.

Semaphores, critical sections are other options. There's a lot of code on the internet

I want to use shared memory to log trace information to the file. Thru my application multiple Dlls are loaded to retrieve information from further Dlls, and the leaf dll retrieve the information from the hardware. In this case i want to trace the information from my applicatio as well as all the loaded Dlls loaded in the applications memory space.

Thanks in advance.
