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