MAGIC(4) — HP-UX

NAME

magic − magic numbers for HP-UX implementations

SYNOPSIS

#include <magic.h>

DESCRIPTION

Magic.h localizes all information about HP-UX "magic numbers" in one file, and thus facilitates 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 LISP_MAGIC	0x10C	/* compiled Lisp */
#define HPE_MAGIC	0x150	/* HPE boot image */

The values for system_id are defined in model(4).

WARNINGS

Cpio files use a different form of magic number that is incompatible with magic(4).

HARDWARE DEPENDENCIES

Series 200, 300, 800
An additional file type is defined:

#define DEMAND_MAGIC0x10B/* demand-load executable */
