GELF_GETCHDR(3)           Libelf Programmer's Manual           GELF_GETCHDR(3)



NAME
       gelf_getchdr - retrieve the class-independent compression header for an
       ELF section with compressed data.


SYNOPSIS
       #include <gelf.h>

       GElf_Chdr *gelf_getchdr (Elf_Scn *scn, GElf_Chdr *dest);


DESCRIPTION
       Retrieve the class-independent compression header for section scn with
       compressed data and store it in dest.  Sections with compressed data
       are indicated with the SHF_COMPRESSED flag.  See libelf(3) for more
       information regarding the compression header.


PARAMETERS
       scn    Section whose compression header will be retrieved. The
              section's SHF_COMPRESSED flag must be set.


       dest   Pointer to a caller-provided GElf_Chdr structure that will
              receive the class-independent compression header for scn.


RETURN VALUE
       On success, this function returns dest.  On failure, it returns NULL
       and sets elf_errno.  If scn is NULL, then NULL is returned and
       elf_errno is not set.
