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 destination 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 definedfor 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 buffer overflow, etc.elf_getdata(3ELF) describes the Elf_Data descriptor, which
the translation routines use as follows:d_buf Both the source and destination must have valid
buffer pointers.d_type 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 programsupplies a d_type value in the source; the

library sets the destination's d_type to the
same value. These values are summarized below.d_size 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 thedestination's d_size member to the actual size
required, after the translation occurs. The source and destination sizes may differ.d_version This member holds the version number of the
objects (desired) in the buffer. The source and destination versions are independent. Translation routines allow the source and destinationbuffers to coincide. 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

Translating buffers of type ELF_T_BYTE does not change the
byte order.For the 64-bit class, replace 32 with 64 as appropriate.
