lgrp_version(3LGRP) Locality Group Library Functions lgrp_version(3LGRP) 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 ver- sion 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 cur- rent 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 ", LGRP_VER_CURRENT); exit(1); } ATTRIBUTES

liblgrp - locality group library SYNOPSIS
cc [ flag... ] file... -llgrp [ library... ] #include <sys/lgrp_user.h> DESCRIPTION
The functions in this library traverse the lgroup (locality group) hierarchy, discover its contents, and set a thread's affinity for an lgroup. A locality group represents the set of CPU-like and memory-like hardware devices that are at most some locality apart from each other. INTERFACES
The shared object liblgrp.so.1 provides the public interfaces defined below. See Intro(3) for additional information on shared object interfaces. lgrp_affinity_get lgrp_affinity_set lgrp_children lgrp_cookie_stale lgrp_cpus lgrp_fini lgrp_home lgrp_init lgrp_latency lgrp_latency_cookie lgrp_mem_size lgrp_nlgrps lgrp_parents lgrp_resourcess lgrp_root lgrp_version lgrp_view FILES
