- NAME
- elf_fsize: elf32_fsize elf64_fsize - return the size of an object file
- type
-
- SYNOPSIS
- cc [flag ...] file ... -lelf [library ...]
-
- #include <libelf.h>
-
- size_t elf32_fsize(Elf_Type type, size_t count, unsigned ver);
- size_t elf64_fsize(Elf_Type type, size_t count, unsigned ver);
-
- #define _LIBELF_XTND_64
- Elf64_Xword elf64_fsize(Elf_Type type, Elf64_Xword count, unsigned ver);
-
- DESCRIPTION
- elf32_fsize gives the size in bytes of the 32-bit file representation of
- count data objects with the given type. The library uses version ver to
- calculate the size [see elf(3E) and elf_version(3E)].
-
- Constant values are available for the sizes of fundamental types.

-
- elf32_fsize returns zero if the value of type or ver is unknown. See
- elf_xlate(3E) for a list of the type values.
-
- The 64-bit class works identically, simply replacing all instances of 32
- in the description and table with 64.

- NOTES
- The use of a size_t in a 32-bit compile with elf64_fsize is unfortunate,
- since that makes it impossible to deal with certain object files. If,
- when the 32-bit app is compiled, _LIBELF_XTND_64 is defined, then the
- function interface changes to have 64-bit fields. If _LIBELF_XTND_64 is
- defined at compile-time, then instead of linking with -lelf, link with
- -lelf_xtnd. There is a corresponding -ldwarf_xtnd. It is essential that
- a 32-bit application compiled with _LIBELF_XTND_64 be *entirely* compiled
- with _LIBELF_XTND_64 defined.

-
- Applications which are built as 64-bit applications can ignore
- _LIBELF_XTND_64: it has no effect on them and 64-bit applications always
- link with -lelf never with -lelf_xtnd.
