cc [ flag … ] file… –llgrp [ library … ] #include <sys/lgrp_user.h> int lgrp_affinity_inherit_set(idtype_t idtype, id_t id, lgrp_aff_inherit_t inherit_flags);
The lgrp_affinity_inherit_set() function sets the lgroup affinity inheritance of the specified process or thread. The lgroup affinities can be inherited by child processes or threads across fork (2), exec(2), pthread_create (3C), and thr_create(3C). By default, they are not inherited across fork(), pthread_create (), and thr_create(), but are inherited across the exec functions for compatibility.
If the idtype is P_PID, the lgroup inheritance is set for all of the threads in the process. The lgroup inheritance is set for the thread in the current process with LWP ID id if idtype is P_LWPID. If id is P_MYID, then the current LWP or process is specified.
The lgrp_aff_inherit_t can be one of the following values:
The lgroup affinity inheritance is set to the default value for the specified process or thread.
The lgroup affinities are not inherited from the specified process or thread.
The lgroup affinities will be inherited by future children of the specified process or thread.
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error.
The lgrp_affinity_inherit_set() function will fail if:
Operation permission is denied to the calling process (see Intro(2)).
An invalid idtype, process or thread ID, or lgroup affinity inheritance was specified.
