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);

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(3ELF) and elf_version(3ELF).

Constant values are available for the sizes of fundamental types:

Elf_Type    File Size    Memory Size
ELF_T_ADDR    ELF32_FSZ_ADDR    sizeof(Elf32_Addr)
ELF_T_BYTE    1    sizeof(unsigned char)
ELF_T_HALF    ELF32_FSZ_HALF    sizeof(Elf32_Half)
ELT_T_OFF    ELF32_FSZ_OFF    sizeof(Elf32_Off)
ELF_T_SWORD    ELF32_FSZ_SWORD    sizeof(Elf32_Sword)
ELF_T_WORD    ELF32_FSZ_WORD    sizeof(Elf32_Word)

elf32_fsize() returns 0 if the value of type or ver is unknown. See elf32_xlatetof(3ELF) for a list of the type values.

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