  24  *
  25  *    Definitions for accessing mach-o headers.  This header wraps the
  26  *    routines defined in osfmk/mach-o/mach_header.c; this is made clear
  27  *    by the existance of the getsectcmdsymtabfromheader() prototype.
  28  *
  29  * NOTE:      The functions prototyped by this header only operate againt
  30  *            32 bit mach headers.  Many of these functions imply the
  31  *            currently running kernel, and cannot be used against mach
  32  *            headers other than that of the currently running kernel.
  33  *
  34  * HISTORY
  35  * 29-Jan-92  Mike DeMoney (mike@next.com)
  36  *      Made into machine independent form from machdep/m68k/mach_header.h.
  37  *      Ifdef'ed out most of this since I couldn't find any references.
