GELF_GETSHDR(3) 					   BSD Library Functions Manual 					   GELF_GETSHDR(3)

NAME
elf32_getshdr, elf64_getshdr, gelf_getshdr -- retrieve the class-dependent section header
LIBRARY
ELF Access Library (libelf, -lelf)
SYNOPSIS
#include <libelf.h> Elf32_Shdr * elf32_getshdr(Elf_Scn *scn); Elf64_Shdr * elf64_getshdr(Elf_Scn *scn); #include <gelf.h> GElf_Shdr * gelf_getshdr(Elf_Scn *scn, GElf_Shdr *shdr);
DESCRIPTION
These functions return a pointer to the ELF Section Header data structure associated with section descriptor scn. Function elf32_getshdr() retrieves a pointer to an Elf32_Shdr structure. Section descriptor scn must be associated with an ELF descriptor of class ELFCLASS32. Function elf64_getshdr() retrieves a pointer to an Elf64_Shdr structure. Section descriptor scn must be associated with an ELF descriptor of class ELFCLASS64. Function gelf_getshdr() copies the values in the section header associated with argument scn to the structure pointed to be argument dst. The GElf_Shdr data structure is described in gelf(3).
RETURN VALUES
Functions elf32_getshdr() and elf64_getshdr() return a valid pointer to the appropriate section header on success or NULL if an error was encountered. Function gelf_getshdr() returns argument dst if successful, or NULL if an error was encountered.
ERRORS
These functions may fail with the following errors: [ELF_E_ARGUMENT] Arguments scn or shdr were NULL. [ELF_E_ARGUMENT] Argument scn was not associated a descriptor for an ELF object. [ELF_E_CLASS] The ELF class associated with the section descriptor scn did not match the class expected by the API.
