elf32_fsize

elf32_fsize(3ELF)                                              ELF Library Functions                                             elf32_fsize(3ELF)

NAME

       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. The library uses version
       ver to calculate the size. See elf(3ELF) and elf_version(3ELF).

       Constant values are available for the sizes of fundamental types:

              Elf_Type  File Size Memory Size
              ELF_T_ADDR     ELF32_FSZ_ADDR sizeof(Elf32_Addr)
              ELF_T_BYTE     1    sizeof(unsigned char)
              ELF_T_HALF     ELF32_FSZ_HALF sizeof(Elf32_Half)
              ELT_T_OFF ELF32_FSZ_OFF  sizeof(Elf32_Off)
              ELF_T_SWORD    ELF32_FSZ_SWORD     sizeof(Elf32_Sword)
              ELF_T_WORD     ELF32_FSZ_WORD sizeof(Elf32_Word)

       elf32_fsize() returns 0 if the value of type or ver is unknown. See elf32_xlatetof(3ELF) for a list of the type values.

       For the 64-bit class, replace 32 with 64 as appropriate.
