Abstract: A data structure for a jointly utilized memory device, in particular, for inter-process communication, in an application system. The memory device includes a memory cell. The data structure includes a management structure, the management structure being configured to hold a pointer object to the memory cell.

Abstract: A data structure for a buffer memory for a multi-producer multi-consumer system. The data structure includes at least one slot for storing data, a first queue, a second queue, a third queue. Each slot of the buffer memory is assigned a unique identifier. At all times, each of the identifiers being assigned either to the first queue or to the second queue or to the third queue.

Abstract: A computer-implemented method for the usage of a jointly utilized memory medium by a user, in particular by a computer-implemented application. The jointly utilized memory medium is divided into at least one partition, each partition being assignable a right of use, in particular a write permission and/or a read permission, a plurality of user groups being assignable to the right of use, the user being a member of a user group, a usage of the jointly utilized memory medium by the user being prevented when the user accesses a first partition of the at least one partition and the user is not a member of one of the user groups assigned to the right of use corresponding to the access.

Abstract: A method for providing a datum in a receive buffer memory. The method includes storing the datum to be provided in the receive buffer memory, and retrieving an old datum from the receive buffer memory, if the receive buffer memory overflows as a result of storing the datum to be provided.
