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.

NAME

       elf_version - coordinate ELF library and application versions

SYNOPSIS

       cc [ flag ... ] file ... -lelf [ library ... ]
       #include <libelf.h>

       unsigned elf_version(unsigned ver);

DESCRIPTION

       As  elf(3ELF) explains, the program, the library, and an object file have independent notions of the latest ELF version. elf_version() lets
       a program query the ELF library's internal version. It further lets the program specify what memory types it uses by giving its own working
       version, ver, to the library. Every program that uses the ELF library must coordinate versions as described below.

       The header <libelf.h> supplies the version to the program with the macro EV_CURRENT. If the library's internal version (the highest version
       known to the library) is lower than that known by the program itself, the library may lack  semantic  knowledge	assumed  by  the  program.
       Accordingly, elf_version() will not accept a working version unknown to the library.

       Passing ver equal to EV_NONE causes elf_version() to return the library's internal version, without altering the working version. If ver is
       a version known to the library, elf_version() returns the previous (or initial) working version	number.  Otherwise,  the  working  version
       remains unchanged and elf_version() returns EV_NONE.

EXAMPLES

       Example 1: A sample display of using the elf_version() function.

       The following excerpt from an application program protects itself from using an older library:

       if (elf_version(EV_CURRENT) == EV_NONE) {
	    /* library out of date */
	    /* recover from error */
       }

NOTES

       The  working  version  should  be  the same for all operations on a particular ELF descriptor. Changing the version between operations on a
       descriptor will probably not give the expected results.
