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.
