NAME

gelf_fsize - calculate the file size of an ELF data structure

SYNOPSIS

#include <gelf.h>

size_t gelf_fsize (Elf *elf, Elf_Type type, size_t count, unsigned int version);

DESCRIPTION

Return the number of bytes needed for the o-disk representation of an array of count elements with type denoted by type. The number of bytes depends on the binary class (ELFCLASS32 or ELFCLASS64) of the given elf. 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

elf: The Elf descriptor that determines the binary class used to compute the file size.
type: The ELF data structure 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, then 0 is returned and elf_errno is set. Integer overflow can occur if the size of type multiplied by count is greater than SIZE_MAX.
