NAME

gelf_offscn - return descriptor for an ELF section at a given file offset

 

SYNOPSIS

#include <gelf.h>

Elf_Scn *gelf_offscn(Elf *elf, GElf_Off offset);

 

DESCRIPTION

gelf_offscn() retrieves the section descriptor for the no-empty section with sh_offset equal to offset. This function will not return descriptors for SHT_NOBITS sections since they are empty by definition.

 

PARAMETERS

elf

Pointer to an ELF descriptor with kind ELF_K_ELF.

offset

The file offset (in bytes) of the section to be retrieved.

 

RETURN VALUE

On success, gelf_offscn() returns a pointer to the Elf_Scn of the no-empty section with a sh_offset matching offset.

On failure, NULL is returned and elf_errno is set to indicate the error. If elf is NULL, then NULL is returned without setting elf_errno.
