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 on-disk representation in a 32-bit or 64-bit ELF file. The on-disk and in-memory representations of Elf_Type are assumed to be the same. See libelf(3) for more information regarding Elf_Type.

Name

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

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.

Reporting Bugs

Report bugs to <elfutils-devel@sourceware.org> or https://sourceware.org/bugzilla/. Libelf 2024-08-14 ELF32_FSIZE(3)

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.
