seanhalle@0 31 /*These are the library functions *called in the application*
seanhalle@0 32 *
seanhalle@0 33 *There's a pattern for the outside sequential code to interact with the
seanhalle@0 34 * VMS_HW code.
seanhalle@2 35 *The VMS_HW system is inside a boundary.. every VSs system is in its
seanhalle@0 36 * own directory that contains the functions for each of the processor types.
seanhalle@0 37 * One of the processor types is the "seed" processor that starts the
seanhalle@0 38 * cascade of creating all the processors that do the work.
seanhalle@0 39 *So, in the directory is a file called "EntryPoint.c" that contains the
seanhalle@0 40 * function, named appropriately to the work performed, that the outside
seanhalle@0 41 * sequential code calls. This function follows a pattern:
seanhalle@2 42 *1) it calls VSs__init()
seanhalle@0 43 *2) it creates the initial data for the seed processor, which is passed
seanhalle@0 44 * in to the function
seanhalle@2 45 *3) it creates the seed VSs processor, with the data to start it with.
seanhalle@2 46 *4) it calls startVSsThenWaitUntilWorkDone
seanhalle@0 47 *5) it gets the returnValue from the transfer struc and returns that
seanhalle@0 48 * from the function
seanhalle@0 49 *
seanhalle@2 50 *For now, a new VSs system has to be created via VSs__init every
seanhalle@0 51 * time an entry point function is called -- later, might add letting the
seanhalle@2 52 * VSs system be created once, and let all the entry points just reuse
seanhalle@0 53 * it -- want to be as simple as possible now, and see by using what makes
seanhalle@0 54 * sense for later..

seanhalle@0 63 * VMS system, then creates one processor from the specified function and
seanhalle@0 64 * puts it into the readyQ. From that point, that one function is resp.
seanhalle@0 65 * for creating all the other processors, that then create others, and so
seanhalle@0 66 * forth.
seanhalle@0 67 *When all the processors, including the seed, have dissipated, then this
seanhalle@0 68 * function returns. The results will have been written by side-effect via
seanhalle@0 69 * pointers read from, or written into initData.
