Abstract
The present invention relates to signal handling in a host operating system process executing code portions of a single- or multi-threaded application and of the embedded guest operating system. When a signal is sent from the host operating system to the operating system process, the signal handler of the guest operating system will be invoked in a deterministic time, independent of the operating system process executing code portions of the application or of the guest operating system or executing system calls of the host operating system in a masked or non-masked operation.
