    function fpSetPriority(Which: cint; Who: cint; What: cint) : cint;

    Description

    fpSetPriority sets the priority with which a process is running. Which process(es) is determined by the Which and Who variables. Which can be one of the predefined constants:

    Prio_Process
    Who is interpreted as process ID
    Prio_PGrp
    Who is interpreted as process group ID
    Prio_User
    Who is interpreted as user ID

    Prio is a value in the range -20 to 20.

    For an example, see FpNice.

    The function returns zero on success, -1 on failure
