NAME

elf_strptr — retrieve a string pointer in a string table

SYNOPSIS

ELF Access Library (libelf, -lelf)
#include <libelf.h>

char *
elf_strptr(Elf *elf, size_t scndx, size_t stroffset);

DESCRIPTION

Function elf_strptr() allows an application to convert a string table offset to a string pointer, correctly translating the offset in the presence of multiple Elf_Data descriptors covering the contents of the section.

Argument elf is a descriptor for an ELF object. Argument scndx is the section index for an ELF string table. Argument stroffset is the index of the desired string in the string table.

RETURN VALUES

Function elf_strptr() returns a valid pointer on success or NULL in case an error was encountered.
