elf_kind - determine file type SYNOPSIS
cc [ flag ... ] file ... -lelf [ library ... ] #include <libelf.h> Elf_Kind elf_kind(Elf *elf); DESCRIPTION
This function returns a value identifying the kind of file associated with an ELF descriptor (elf). Defined values are below: ELF_K_AR 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. ELF_K_COFF The file is a COFF object file. elf_begin(3ELF) 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(), 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. ATTRIBUTES

elf32_getehdr, elf32_newehdr, elf64_getehdr, elf64_newehdr - retrieve class-dependent object file header SYNOPSIS
cc [ flag ... ] file ... -lelf [ library ... ] #include <libelf.h> Elf32_Ehdr *elf32_getehdr(Elf *elf); Elf32_Ehdr *elf32_newehdr(Elf *elf); Elf64_Ehdr *elf64_getehdr(Elf *elf); Elf64_Ehdr *elf64_newehdr(Elf *elf); DESCRIPTION
For a 32-bit class file, elf32_getehdr() returns a pointer to an ELF header, if one is available for the ELF descriptor elf. If no header exists for the descriptor, elf32_newehdr() allocates a clean one, but it otherwise behaves the same as elf32_getehdr(). It does not allo- cate a new header if one exists already. If no header exists for elf32_getehdr(), one cannot be created for elf32_newehdr(), a system error occurs, the file is not a 32-bit class file, or elf is NULL, both functions return a null pointer. For the 64-bit class, replace 32 with 64 as appropriate. The header includes the following members: unsigned char e_ident[EI_NIDENT]; Elf32_Half e_type; Elf32_Half e_machine; Elf32_Word e_version; Elf32_Addr e_entry; Elf32_Off e_phoff; Elf32_Off e_shoff; Elf32_Word e_flags; Elf32_Half e_ehsize; Elf32_Half e_phentsize; Elf32_Half e_phnum; Elf32_Half e_shentsize; Elf32_Half e_shnum; Elf32_Half e_shstrndx; The elf32_newehdr() function automatically sets the ELF_F_DIRTY bit. See elf_flagdata(3ELF). An application can use elf_getident() to inspect the identification bytes from a file. An application can use elf_getshnum() and elf_getshstrndx() to obtain section header information. The location of this section header information differs between standard ELF files to those that require Extended Sections. ATTRIBUTES
