- determine file type
cc [ flag ... ] file ... -lelf [ library ... ] #include <libelf.h> Elf_Kind elf_kind(Elf *elf);
This function returns a value identifying the kind of file associated with an ELF descriptor (elf). Defined values are below:
The file is an archive [see ar.h(3HEAD)]. An ELF descriptor may also be associated with an archive member, not the archive itself, and then elf_kind() identifies the member's type.
The file is a COFF object file. elf_begin(3ELF) describes the library's handling for COFF files.
The file is an ELF file. The program may use elf_getident() to determine the class. Other functions, such as elf32_getehdr(), are available to retrieve other file information.
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.
