NAME
        CreateNewProc -- Create a new process (V36)

   SYNOPSIS
        process = CreateNewProc(tags)
        D0                       D1

        struct process *createnewproc(struct tagitem *)

        process = CreateNewProcTagList(tags)
        D0                              D1

        struct process *createnewproctaglist(struct tagitem *)

        process = CreateNewProcTags(Tag1, ...)

        struct process *createnewproctags(ulong, ...)

   FUNCTION
        This creates a new process according to the tags passed in.  See
        dos/dostags.h for the tags.

        You must specify one of NP_Seglist or NP_Entry.  NP_Seglist takes a
        seglist (as returned by LoadSeg()).  NP_Entry takes a function
        pointer for the routine to call.

        There are many options, as you can see by examining dos/dostags.h.
        The defaults are for a non-CLI process, with copies of your
        currentdir, homedir (used for progdir:), priority, consoletask,
        windowptr, and variables.  The input and output filehandles default
        to opens of NIL:, stack to 4000, and others as shown in dostags.h.
        This is a fairly reasonable default setting for creating threads,
        though you may wish to modify it (for example, to give a descriptive
        name to the process.)

        CreateNewProc() is callable from a task, though any actions that
        require doing Dos I/O (DupLock() of currentdir, for example) will not
        occur.

        NOTE: if you call CreateNewProc() with both NP_Arguments, you must
        not specify an NP_Input of NULL.  When NP_Arguments is specified, it
        needs to modify the input filehandle to make readargs() work properly.

   INPUTS
        tags - a pointer to a tagitem array.

   RESULT
        process - The created process, or NULL.  Note that if it returns
                  NULL, you must free any items that were passed in via
                  tags, such as if you passed in a new current directory
                  with NP_CurrentDir.

   BUGS
        In V36, NP_Arguments was broken in a number of ways, and probably
        should be avoided (instead you should start a small piece of your
        own code, which calls runcommand() to run the actual code you wish
        to run).  In V37, NP_Arguments works, though see the note above.
