NetBSD 6.1.5 - man page for gelf_getshdr (netbsd section 3)

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

NAME
     elf32_getshdr, elf64_getshdr, gelf_getshdr -- retrieve the class-dependent section header

LIBRARY
     library ``libelf''

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 sec-
     tion header on success or NULL if an error was encountered.

     Function gelf_getshdr() returns argument dst if successful, or NULL if an error was encoun-
     tered.

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.
