elf_fsize(S)


elf_fsize: elf32_fsize -- return the size of an object file type

Syntax

cc [flag . . . ] file . . . -lelf [library] . . .

#include <libelf.h>

size_t elf32_fsize(Elf_Type type, size_t count, unsigned ver);

Description

elf32_fsize(S) gives the size in bytes of the 32-bit file representation of count data objects of the specified type. The library uses version ver to calculate the size (see elf(S) and elf_version(S)).

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)

Return values

elf32_fsize( ) returns zero if the value of type or ver is unknown. See elf_xlate(S) for a list of the type values.

Diagnostics

Error conditions are identified through the routine elf_error(S).
