| 23 | * File: kern/mach_header.h | |
| 24 | * | |
| 91447636 A |
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. | |

| 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. | |
