elf32_fsize - Man Page
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 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.
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.
