NAME

elf32_fsize, elf64_fsize - calculate the file size of an ELF data structure

 

SYNOPSIS

#include <libelf.h>

size_t elf32_fsize(Elf_Type type, size_t count, unsigned int version);
size_t elf64_fsize(Elf_Type type, size_t count, unsigned int version);

 

DESCRIPTION

Given an Elf_Type representation of a core ELF structure as well as the number of items, return the number of bytes needed for the o-disk representation in a 3-bit or 6-bit ELF file. The o-disk and i-memory representations of Elf_Type are assumed to be the same. See libelf(3) for more information regarding Elf_Type.

 

PARAMETERS

type

The ELF data structure type for which the file size is to be calculated.

count

The number of elements of the specified type.

version

The ELF version. This should be set to EV_CURRENT, which is the only valid value.

 

RETURN VALUE

The size in bytes of the specified count and type of data structure. If version is not set to EV_CURRENT or type is not a valid Elf_Type, return 0 and set a libelf error code. Integer overflow can occur if the size of type multiplied by count is greater than SIZE_MAX.
