elf_version

elf_version(3E) 														   elf_version(3E)

NAME

       elf_version() - coordinate ELF library and application versions

SYNOPSIS

       Command: [flag]... file... [library]...

DESCRIPTION

       As  elf(3E)  explains,  the  program, the library, and an object file have independent notions of the "latest" ELF version.  lets a program
       determine the ELF library's It further lets the program specify what memory types it uses by giving its own ver,  to  the  library.   Every
       program that uses the ELF library must coordinate versions as described below.

       The  header  file  supplies  the  version to the program with the macro If the library's internal version (the highest version known to the
       library) is lower than that known by the program itself, the library may lack semantic knowledge assumed by the program.  Accordingly, will
       not accept a working version unknown to the library.

       Passing a ver equal to causes to return the library's internal version, without altering the working version.  If ver is a version known to
       the library, returns the previous (or initial) working version number.  Otherwise, the working version remains unchanged and returns

EXAMPLES

       The following excerpt from an application program protects itself from using an older library.

	      if (elf_version(EV_CURRENT) == EV_NONE)
	      {
		  /* library out of date */
		  /* recover from error */
	      }

WARNINGS

       The working version should be the same for all operations on a particular ELF descriptor.  Changing the version	between  operations  on  a
       descriptor will probably not give the expected results.
