elf_xlate(3E) elf_xlate(3E) NAME
elf32_xlatetof, elf32_xlatetom, elf64_xlatetof, elf64_xlatetom - class-dependent data translation for elf32 and elf64 files, respectively SYNOPSIS
[flag... ] file... [library] ... DESCRIPTION
translates various data structures from their 32-bit class file representations to their memory representations; translates various data structures from their 64-bit class file representations to their memory representations; and provide the inverse. This conversion is par- ticularly 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 entry (see elf_getident(3E)). If the data can be trans- lated, the functions return dst. Otherwise, they return null because an error occurred, such as incompatible types, destination buffer overflow, and so forth. elf_getdata(3E) describes the Elf_Data descriptor, which the translation routines use as follows. Both the source and destination must have valid buffer pointers. This member's value specifies the type of the data to which points and the type of data to be created in the destination. The program supplies a value in the source; the library sets the destination's 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 member to the actual size required, after the translation occurs. The source and destination sizes may differ. This member holds version number of the objects (desired) in the buffer. The source and destination versions are independent. Translation routines allow the source and destination buffers to coincide. That is, may equal Other cases where the source and destination buffers overlap give undefined behavior.
