 LGRP_VERSION 3LGRP "Apr 16, 2003"
 NAME
lgrp_version - coordinate library and application versions
 SYNOPSIS

cc [ flag .\|.\|. ] file.\|.\|. -llgrp [ library .\|.\|. ]
#include <sys/lgrp_user.h>

int lgrp_version(const int version);


 DESCRIPTION

The lgrp_version() function takes an interface version number,
version, as an argument and returns an lgroup interface version. The
version argument should be the value of LGRP_VER_CURRENT bound to
the application when it was compiled or LGRP_VER_NONE to find out the
current lgroup interface version on the running system.
 RETURN VALUES

If version is still supported by the implementation, then
lgrp_version() returns the requested version. If LGRP_VER_NONE is
returned, the implementation cannot support the requested version. The
application should be recompiled and might require further changes.

If version is LGRP_VER_NONE, lgrp_version() returns the
current version of the library.
 EXAMPLES

Example 1 Test whether the version of the interface used by the caller is
supported.

The following example tests whether the version of the interface used by the
caller is supported:

#include <sys/lgrp_user.h>

if (lgrp_version(LGRP_VER_CURRENT) != LGRP_VER_CURRENT) {
 fprintf(stderr, "Built with unsupported lgroup interface %d\en",
 LGRP_VER_CURRENT);
 exit (1);
}
