NAME
magic - magic numbers for HP-UX implementations
SYNOPSIS
#include <magic.h>
DESCRIPTION
The magic.h file localizes all information about
HP-UX ‘‘magic numbers’’ in one file, thus facilitating
uniform treatment of magic numbers. This file specifies the location of the magic number in a file (always
the start of the file) and the structure of the magic number:
struct magic_number {
unsigned short system_id;
unsigned short file_type;
};
typedef struct magic_number MAGIC;
magic.h includes definitions for the system
IDs of all HP machines running HP-UX, and file types that
are common to all implementations. There may be additional implementation-dependent file types. The
predefined file types are:
/* for object code files */
#define RELOC_MAGIC 0x106 /* relocatable only */
#define EXEC_MAGIC 0x107 /* normal executable */
#define SHARE_MAGIC 0x108 /* shared executable */
#define DEMAND_MAGIC 0x10B /* demand-load executable */
#define LISP_MAGIC 0x10C /* compiled Lisp */
#define DL_MAGIC 0x10D /* dynamic load library */
#define SHL_MAGIC 0x10E /* shared library */
#define HPE_MAGIC 0x150 /* HPE boot image */
The values for system_id are defined in model (4).
WARNINGS
Files managed by
cpio use a different form of magic number that is incompatible with <
magic.h>.
