NAME

elf_end − finish using an object file

SYNOPSIS

cc [flag ...] file ... −lelf [library ...]

#include <libelf.h>
int elf_end(Elf ∗elf);

DESCRIPTION

A program uses elf_end to terminate an ELF descriptor, elf, and to deallocate data associated with the descriptor. Until the program terminates a descriptor, the data remain allocated. elf should be a value previously returned by elf_begin; a null pointer is allowed as an argument, to simplify error handling.  If the program wishes to write data associated with the ELF descriptor to the file, it must use elf_update before calling elf_end. 

As elf_begin(3E) explains, a descriptor can have more than one activation.  ­Calling elf_end removes one activation and returns the remaining activation count.  The library does not terminate the descriptor until the activation count reaches zero.  Consequently, a zero return value indicates the ELF descriptor is no longer valid.
