## NAME

memkind\_dax\_kmem - DAX KMEM memory memkind operations.\
 **Note:** This is EXPERIMENTAL API. The functionality and the header file itself can be changed (including non-backward compatible changes) or removed.

## SYNOPSIS

**int memkind\_dax\_kmem\_all\_get\_mbind\_nodemask(struct memkind** *\*kind***, unsigned long** *\*nodemask***, unsigned long** *maxnode***);**\

## DESCRIPTION

DAX KMEM memory memkind operations.

**memkind\_dax\_kmem\_all\_get\_mbind\_nodemask**() sets the *nodemask* bits to one that correspond to the all persistent memory NUMA nodes in the system. All other bits up to *maxnode* are set to zero. The *nodemask* can be used in conjunction with the [**mbind**(2)](/mbind/2.md) system call.
