ELF_VERSION(3)		 BSD Library Functions Manual		ELF_VERSION(3)

NAME
     elf_version -- retrieve or	set ELF	library	operating version

LIBRARY
     ELF Access	Library	(libelf, -lelf)

SYNOPSIS
     #include <libelf.h>

     unsigned int
     elf_version(unsigned int version);

DESCRIPTION
     The elf_version() function	is used	to query the current operating version
     of	the ELF	library, and to	inform the ELF library about the application's
     desired operating version.

     If	the argument version is	EV_NONE, the elf_version() function returns
     the currently configured operating	version	for the	ELF library.

     If	the argument version is	not EV_NONE, and if argument version is	sup-
     ported by the ELF library,	function elf_version() sets the	library's op-
     erating version to	version, and returns the previous value	of the operat-
     ing version.  If argument version cannot be supported, then the
     elf_version() function returns EV_NONE.

RETURN VALUES
     The elf_version() function	returns	the currently configured ELF library
     version, or EV_NONE if an unsupported version is requested.

EXAMPLES
     An	application program would inform the ELF library about its desired op-
     erating version and check for an error using the following	code snippet:

	   if (elf_version(EV_CURRENT) == EV_NONE)
		   err(EXIT_FAILURE, "ELF library too old");

ERRORS
     Function elf_version() may	fail with the following	error:

     [ELF_E_VERSION]   An unsupported library version number was requested.
