A method, apparatus and program storage device for enabling the reading of data from a named pipe by a reader process while minimizing the use of system resources in an information handling system in which client and reader processes write data to and read data from a named pipe by issuing function calls to an operating system. A first reader process creates a named pipe if it does not already exist and issues a read function call to the operating system specifying the named pipe to attempt to read data from the pipe. If the read operation is successful, the first reader process repeats the step of issuing the read function call. Otherwise, the first reader process issues an activate-on-receipt function call to the operating system, specifying the named pipe, a new reader process to be activated upon the receipt of data by the named pipe and, optionally, data being passed from the first reader process to the new reader process, and then terminates. The operating system activates the new reader process in response to the activate-on-receipt function call upon the receipt of data by the named pipe. Typically, the new reader process is a new instantiation of the first reader process that upon being activated performs the same steps as the first reader process.

An interprocess communications platform enables individual processes to request and exchange data in a shared memory space, mediated by a communications engine. Processes, such as applications or other software running under an operating system or in a network, register to blocks of a shared memory space via an administrative memory space which tracks pointers, handles and other indicators of memory areas populated by individual processes. When one process requests access to a variable, pointer or other data generated by another process, the request is mediated by the communications engine. The communications engine may locate the target data belonging to the other process in the shared memory space, via a lookup of relative addressing in a separate administrative memory space. The communications engine, memory management objects and other resources may then lock the portion of the shared memory space allocated to the target process to permit the requesting process to access the data. Data may therefore be exchange between given processes while maintaining data integrity, and also may be cached in the shared memory space or elsewhere by the communications engine to further increase efficiency. Available memory in the shared memory space may be managed using the so-called buddy system or other heap or other management techniques. No named pipes or similar mechanisms under an operating system need be invoked.
