31 * Definitions for accessing mach-o headers. This header wraps the
32 * routines defined in osfmk/mach-o/mach_header.c; this is made clear
33 * by the existance of the getsectcmdsymtabfromheader() prototype.
34 *
35 * NOTE: The functions prototyped by this header only operate againt
36 * 32 bit mach headers. Many of these functions imply the
37 * currently running kernel, and cannot be used against mach
38 * headers other than that of the currently running kernel.

40 * HISTORY
41 * 29-Jan-92 Mike DeMoney (mike@next.com)
42 * Made into machine independent form from machdep/m68k/mach_header.h.
43 * Ifdef'ed out most of this since I couldn't find any references.
