Versioning Sections

Objects created by the link-editor can contain two types of versioning information.

  • Version definitions provide associations of global symbols and are implemented using sections of type SHT_SUNW_verdef and SHT_SUNW_versym.

  • Version dependencies indicate the version definition requirements from other object dependencies and are implemented using sections of type SHT_SUNW_verneed and SHT_SUNW_versym.

The structures that form these sections are defined in sys/link.h. Sections that contain versioning information are named .SUNW_version.
