GELF_GETEHDR(3)            Library Functions Manual            GELF_GETEHDR(3)

NAME
     elf32_getehdr, elf64_getehdr, gelf_getehdr -- retrieve the object file
     header

LIBRARY
     ELF Access Library (libelf, -lelf)

SYNOPSIS
     #include <&lt;libelf.h>&gt;

     Elf32_Ehdr *
     elf32_getehdr(Elf *elf);

     Elf64_Ehdr *
     elf64_getehdr(Elf *elf);

     #include <&lt;gelf.h>&gt;

     GElf_Ehdr *
     gelf_getehdr(Elf *elf, GElf_Ehdr *dst);

DESCRIPTION
     These functions retrieve the ELF object file header from the ELF
     descriptor elf and return a translated header descriptor to their
     callers.

     Functions elf32_getehdr() and elf64_getehdr() return a pointer to the
     appropriate class-specific header descriptor if it exists in the file
     referenced by descriptor elf.  These functions return NULL if an ELF
     header was not found in file elf.

     Function gelf_getehdr() stores a translated copy of the header for ELF
     file elf into the descriptor pointed to by argument dst.  It returns
     argument dst if successful or NULL in case of failure.

RETURN VALUES
     These functions return a pointer to a translated header descriptor if
     successful, or NULL on failure.

ERRORS
     These functions can fail with the following errors:

     [ELF_E_ARGUMENT]  The argument elf was null.

     [ELF_E_ARGUMENT]  Argument elf was not a descriptor for an ELF file.

     [ELF_E_ARGUMENT]  The elf class of descriptor elf was not recognized.

     [ELF_E_ARGUMENT]  Argument dst was null.

     [ELF_E_CLASS]     The ELF class of descriptor elf did not match that of
                       the API function being called.

     [ELF_E_HEADER]    ELF descriptor elf does not have an associated header.

     [ELF_E_RESOURCE]  An out of memory condition was detected during
                       execution.

     [ELF_E_SECTION]   The ELF descriptor in argument elf did not adhere to
                       the conventions used for extended numbering.

     [ELF_E_VERSION]   The ELF descriptor elf had an unsupported ELF version
                       number.
