Module Name:

    tsecomm.c

Abstract:

    Common security definitions and routines.

    This module defines macros that provide a mode-independent
    interface for security test procedures.

    The mode must be specified by defining one, but not both,
    of:
         _TST_USER_    (for user mode tests)
         _TST_KERNEL_  (for kernel mode tests)

Author:

    Jim Kelly       (JimK)     23-Mar-1990

Environment:

    Test of security.
