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.

ATTRIBUTES

For an explanation of the terms used in this section, see attributes(7).
