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

Syntax

#include <libelf.h>

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

Description

elf32_fsize(S-osr5) 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-osr5) and elf_version(S-osr5)).

Constant values are available for the sizes of fundamental types.

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)

Return values

elf32_fsize( ) returns zero if the value of type or ver is unknown. See elf_xlate(S-osr5) for a list of the type values.

Diagnostics

Error conditions are identified through the routine elf_error(S-osr5).
