elf_fsize(3E)

NAME

elf32_fsize, elf64_fsize — return the size of an object file type for elf32 files, return the size of an object file type for elf64 files, respectively.

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(3E) and elf_version(3E)).

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 zero if the value of type or ver is unknown. See elf_xlate(3E) for a list of the type values.

elf64_fsize gives the size in bytes of the 64-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.

Elf_Type	File Size	Memory Size
`ELF_T_ADDR`	`ELF64_FSZ_ADDR`	`sizeof(Elf64_Addr)`
`ELF_T_BYTE`	`1`	`sizeof(unsigned char)`
`ELF_T_HALF`	`ELF64_FSZ_HALF`	`sizeof(Elf64_Half)`
`ELT_T_OFF`	`ELF64_FSZ_OFF`	`sizeof(Elf64_Off)`
`ELF_T_SWORD`	`ELF64_FSZ_SWORD`	`sizeof(Elf64_Sword)`
`ELF_T_WORD`	`ELF64_FSZ_WORD`	`sizeof(Elf64_Word)`

elf64_fsize returns zero if the value of type or ver is unknown. See elf_xlate(3E) for a list of the type values.
