    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\n",
           LGRP_VER_CURRENT);
       exit (1);
    }
