elftc_version3

Usage

Library

library “libelftc”

Overview

Function elftc_version() returns a project-wide identifier string that encodes the source revision of the project source tree.

The returned identifier has four space-separated fields:

Project-Name

This is always “elftoolchain”.

Project-Branch

The branch name for the project source tree.

Build-OS

The operating system that the tool chain was compiled for.

Version-Number

A tree-wide version number extracted from the version control system in use.

Return values

Function elftc_program_version() returns a pointer to an internal character buffer.

Examples

To retrieve and print the current toolchain version identifier, use:

#include <sys/types.h>
#include <libelftc.h>
(void) printf("%s\n", elftc_version());

On the HEAD branch of the project's sources, when checked out using Subversion and compiled on a NetBSD host, this would print:

where REVINFO would be the current revision information for the project source tree.

Errors

Function elftc_program_version() always succeeds.
