Abstract

The invention relates to a method and a device for controlling access to multiple applications which are each implemented as a client application in an operating system environment of a data processing device from a shared memory system. The problem addressed by the invention is that of providing an improved method and an improved device for controlling access to multiple applications which are each implemented as a client application in an operating system environment of a data processing device from a shared memory system, which allow an efficient exchange of data for input/output. In particular, interaction with multimedia data in such an operating environment should be optimized. The invention comprises the details of a method for controlling access to multiple applications which are each implemented as a client application in an operating system environment of a data processing device from a shared memory system which is constructed in the form of multiple memory blocks in the operating system environment, which are each assigned to one of the client applications.
