ELF32_FSIZE 3ELF "Jul 11, 2001"
NAME
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.
