Elf_Kind elf_kind(Elf * elf);
This function returns a value identifying the kind of file associated with
an ELF descriptor elf. The currently defined values are
shown below.
| ELF_K_AR | The file is an archive [see the ar file format]. An ELF descriptor may also be associated with an archive member, not the archive itself, and then elf_kind identifies the member's type. |
| ELF_K_COFF | The file is a COFF object file. elf_begin describes the library's handling for COFF files. |
| ELF_K_ELF | The file is an ELF file. The program may use elf_getident to determine the class. Other functions, such as elf32_getehdr and elf64_getehdr, are available to retrieve other file information. |
| ELF_K_NONE | This indicates a kind of file unknown to the library. |
Other values are reserved, to be assigned as needed to new kinds of files. elf should be a value previously returned by elf_begin. A null pointer is allowed, to simplify error handling, and causes elf_kind to return ELF_K_NONE.
| elf | An ELF descriptor previously returned from elf_begin. |
