# NAME

elf_strptr — retrieve a string pointer in a string table

# LIBRARY

ELF Access Library (libelf, -lelf)

# SYNOPSIS

#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.
