VMS Help POSIX Threads, PTHREAD routines, pthread_attr_getinheritsched, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    This routine obtains the value of the inherit scheduling
    attribute from the specified thread attributes object. The
    inherit scheduling attribute specifies whether threads created
    using the attributes object inherit the scheduling attributes of
    the creating thread, or use the scheduling attributes stored in
    the attributes object that is passed to pthread_create().
