VMS Help RTL Routines, LIB$, LIB$GET_EF  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Get Event Flag routine allocates one local event flag from
    a processwide pool and returns the number of the allocated flag
    to the caller. If no flags are available, LIB$GET_EF returns an
    error as its function value.

    Format

      LIB$GET_EF  event-flag-number
