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. ATTRIBUTES

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 */ } ATTRIBUTES

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. SunOS 5.10 11 Jul 2001 elf_version(3ELF)
