The present invention discloses a method and system for streaming an information stream from a producer to N consumers in a multi-process environment. An inter-process communication (IPC) channel containing a shared memory is provided between the producer and at least one of N consumers. The information stream is written into the shared memory by way of a producer-side interface. The information stream is read from the shared memory by way of a consumer-side interface.

Information streaming in a multi-process system using shared memory

A method for simulating an interrupt based application programming interface in a computer system, wherein a trap driver hooks to a real mode interrupt chain comprising at least one interrupt service routine for execution in a real mode of a central processing unit. The trap driver waits for a simulated real mode interrupt, and executes an interface function in a protected mode of the central processing unit if the simulated real mode interrupt specifies the application programming interface. Otherwise, the trap driver chains the simulated real mode interrupt to a next interrupt service routine in the real mode interrupt chain.
