elf_fsize(3elf)


elf_fsize: elf32_fsize, elf64_fsize -- return the size of an object file type

Synopsis

   cc [flag . . . ] file . . . -lelf [library] . . .
   

#include <libelf.h>

size_t elf32_fsize(Elf_Type type, size_t count, unsigned ver); size_t elf64_fsize(Elf_Type type, size_t count, unsigned ver);

Description

elf32_fsize gives the size in bytes of the 32-bit file representation of count data objects with the given type. elf64_fsize gives the size in bytes of the 64-bit file representation of count data objects with the given type. The library uses version ver to calculate the size [see Intro(3elf) and elf_version(3elf)].

Constant values are available for the sizes of fundamental types.

elf32_fsize and elf64_fsize return zero if the value of type or ver is unknown. See elf_xlate(3elf) for a list of the type values.
