Device for the utilization of exported pseudosockets

A method for utilizing a remote procedure call of open systems for calling remote stations from a single processor of a computer system utilizing a proprietary operating system and having an open subsystem, said method comprising the following steps:

• setting of a first semaphore to a state P by the proprietary operating system, and setting of a second semaphore to a state P by the open subsystem;
• coding of a function to be executed into a format given by a service routine of the proprietary system;
• writing this coded function into a segment of shared memory;
• setting of the second semaphore to state V;
• activation, by the setting to state V of the second semaphore, of a socket server operating in the open subsystem;
• decoding by the socket server of the coded function contained in the segment and simultaneous setting to state P of a third semaphore by the proprietary operating system;
• execution of the decoded function by the remote station;
• reception of the result by the open subsystem and recoding of this result into the specific format;
• rewriting of the encoded result into the shared memory segment;
• setting to state V the third semaphore, thus activating the service routine and the setting to state P of the second semaphore, thus causing the socket server to be put on hold;
• interpretation by this service routine of the result of the function;
• and
• setting to state V of the first semaphore to permit other users of the proprietary operating system to do other work.
