dg_mem_affinity_attr(3T)          SDK R4.11         dg_mem_affinity_attr(3T)


NAME
       dgmemaffinityattrinit, dgmemsetcpuidset,
       dgmemgetcpuidset, dgmemsetminimumlevel,
       dgmemgetminimumlevel - memory affinity attributes objects

SYNOPSIS
       #include <sys/dgcpu.h>
       #include <sys/dgmemaffinity.h>

       int dgmemaffinityattrinit(attrptr)
       dgmemaffinityattrt *attrptr;

       int dgmemsetcpuidset(attrptr, idsetptr)
       dgmemaffinityattrt *attrptr;
       const dgcpuidsett *idsetptr;

       int dgmemgetcpuidset( attrptr, idsetptr)
       dgmemaffinityattrt *attrptr;
       dgcpuidsett *idsetptr;

       int dgmemsetminimumlevel( attrptr, minlevel)
       dgmemaffinityattrt *attrptr;
       int minlevel;

       int dgmemgetminimumlevel( attrptr, minlevelptr)
       dgmemaffinityattrt *attrptr;
       int *minlevelptr;

   where:
       attrptr    A pointer to a memory affinity attributes object
       idsetptr  A pointer to a CPU ID set
       minlevel   The minimum allowed level attribute
       minlevelptr
                   A pointer to a location to receive the minimum allowed
                   level attribute

DESCRIPTION
       The functions that manipulate memory affinity attributes are copies
       of the functions for CPU affinity attributes, except they operate on
       memory affinity objects instead of CPU affinity objects.  Please
       refer to the corresponding CPU affinity manual page for a description
       of the functionality and diagnostics.
