  32  *
  33  *      Definitions for accessing mach-o headers.  This header wraps the
  34  *      routines defined in osfmk/mach-o/mach_header.c; this is made clear
  35  *      by the existance of the getsectcmdsymtabfromheader() prototype.
  36  *
  37  * NOTE:        The functions prototyped by this header only operate againt
  38  *              32 bit mach headers.  Many of these functions imply the
  39  *              currently running kernel, and cannot be used against mach
  40  *              headers other than that of the currently running kernel.
  41  *
  42  * HISTORY
  43  * 29-Jan-92  Mike DeMoney (mike@next.com)
  44  *      Made into machine independent form from machdep/m68k/mach_header.h.
  45  *      Ifdef'ed out most of this since I couldn't find any references.
