Definition of AXF ELF Header:
#define EI_NIDENT 16
typedef struct {
unsigned char e_ident[EI_NIDENT];
// file info
Elf32_Half e_type;
// type of file
Elf32_Half e_machine;
// target processor
Elf32_Word e_version;
// version #
Elf32_Addr e_entry;
// program entry point
Elf32_Off e_phoff;
// offset of program header
Elf32_Off e_shoff;
// offset of section header table
Elf32_Word e_flags;
// processor-specific flags
Elf32_Half e_ehsize;
// ELF header’s size
Elf32_Half e_phentsize;
// entry size in pgm header tbl
Elf32_Half e_phnum;
// # of entries in pgm header
Elf32_Half e_shentsize;
// entry size in sec header tbl
Elf32_Half e_shnum;
// # of entries in sec header tbl
Elf32_Half e_shstrndx;
// sec header tbl index of str tbl
} Elf32_Ehdr;
