NAME
elf32_xlatetof, elf32_xlatetom, elf64_xlatetof, elf64_xlatetom - class-dependent data translation SYNOPSIS
cc [ flag ... ] file... -lelf [ library ... ] #include <libelf.h> 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, unsigned encode); Elf_Data *elf64_xlatetom(Elf_Data *dst, const Elf_Data *src, unsigned encode); DESCRIPTION
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 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 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 destina- tion. 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. d_size This member holds the total size, in bytes, of the memory occupied by the source data and the size allocated for the destina- tion 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 des- tination sizes may differ. d_version This member holds the version number of the objects (desired) in the buffer. The source and destination versions are indepen- dent. Translation routines allow the source and destination buffers to coincide. That is, dst->d_buf may equal src->d_buf. Other cases where the source and destination buffers overlap give undefined behavior.
