1. A method for high speed interprocess communications comprising the steps of:

  • detecting a previously created shared region of RAM;

    if a shared region of RAM is not detected, creating and configuring a shared region of RAM for storing accumulated data;

    attaching first and second processes to a message buffer in the shared region of random access memory (RAM) exclusive of operating system kernel space, each said process having a message list that is a message queue;

    accumulating message data from said first process in a location in said message buffer;

    said first process adding to said message list of said second process a memory offset corresponding to said location in said message buffer; and

    ,manipulating in said second process said accumulated data at said location corresponding to said offset,whereby said accumulated message data is transferred from said first process to said second process with minimal data transfer overhead.
