`#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.
