       Elf_Data *elf32_xlatetof(Elf_Data *dst, const Elf_Data *src,
	    unsigned encode);

       Elf_Data *elf32_xlatetom(Elf_Data *dst, const Elf_Data *src,
	    unsigned encode);

       Elf_Data *elf64_xlatetof(Elf_Data *dst, const Elf_Data *src,

       Elf_Data *elf64_xlatetom(Elf_Data *dst, const Elf_Data *src,
	    unsigned encode);

       elf32_xlatetom() translates various data structures from	 their	32-bit
       class   file   representations	to   their   memory   representations;
       elf32_xlatetof() provides the inverse. This conversion is  particularly
       important  for  cross development environments. src is a pointer to the
       source buffer that holds the original data; dst is a pointer to a  des‐
       tination	 buffer	 that  will hold the translated copy. encode gives the
       byte encoding in which the file objects are to be represented and  must
       have   one  of  the  encoding  values  defined  for  the	 ELF  header's
       e_ident[EI_DATA] entry (see elf_getident(3ELF)). If  the	 data  can  be
       translated,  the	 functions  return  dst.  Otherwise,  they return NULL
       because an error occurred, such as incompatible types, destination buf‐
       fer overflow, etc.

       elf_getdata(3ELF) describes the Elf_Data descriptor, which the transla‐
       tion routines use as follows:

		    Both the source and destination  must  have	 valid	buffer

		    This  member's  value  specifies  the  type of the data to
		    which d_buf points and the type of data to be  created  in
		    the	 destination.  The  program supplies a d_type value in
		    the source; the library sets the destination's  d_type  to
		    the same value. These values are summarized below.

		    This  member holds the total size, in bytes, of the memory
		    occupied by the source data and the size allocated for the
		    destination	 data.	If the destination buffer is not large
		    enough, the routines do not change its original  contents.
		    The	 translation  routines	reset the destination's d_size
		    member to the actual size required, after the  translation
		    occurs. The source and destination sizes may differ.

		    This  member  holds	 the  version  number  of  the objects
		    (desired) in the buffer.  The source and destination  ver‐
		    sions are independent.

       Translation  routines allow the source and destination buffers to coin‐
       cide. That is, dst→d_buf may equal src→d_buf.  Other  cases  where  the
       source and destination buffers overlap give undefined behavior.

	 Elf_Type	32-Bit Memory Type
	 ELF_T_ADDR	Elf32_Addr
	 ELF_T_BYTE	unsigned char
	 ELF_T_DYN Elf32_Dyn
	 ELF_T_EHDR	Elf32_Ehdr
	 ELF_T_HALF	Elf32_Half
	 ELT_T_OFF Elf32_Off
	 ELF_T_PHDR	Elf32_Phdr
	 ELF_T_REL Elf32_Rel
	 ELF_T_RELA	Elf32_Rela
	 ELF_T_SHDR	Elf32_Shdr
	 ELF_T_SWORD	Elf32_Sword
	 ELF_T_SYM Elf32_Sym
	 ELF_T_WORD	Elf32_Word

       Translating buffers of type ELF_T_BYTE does not change the byte order.

       For the 64−bit class, replace 32 with 64 as appropriate.
