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 com-
     pressed data and store it in dest.	 Sections with compressed data are indi-
     cated with the SHF_COMPRESSED flag.  See libelf(3) for more information re-
     garding 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.
