NAME

get_mempolicy − get the current process’ or memory address’ NUMA policy

SYNOPSIS

int sys_get_mempolicy (int *policy, unsigned long *nmask, unsigned long maxnode, unsigned long addr, unsigned long flags);

DESCRIPTION

get_mempolicy retrieves the NUMA policy of the current process or a memory address specified by addr. The memory policy defines which node memory is allocated to for the process. The policy is stored in policy when non-zero, with an associated nmask. maxnode is the maximum bit number plus one that can be stored into nmask. The bit number is rounded to a multiple of unsigned long. The only valid value other than zero for flags is MPOL_F_ILNODE. This value is only valid when the policy being retrieved is MPOL_INTERLEAVE. When this flag is specified, an unsigned long with the next node that would be used for interleaving is returned in nodemask.

RETURN VALUE

get_mempolicy returns 0 on success; otherwise, it returns one of the errors listed in the "Errors" section.

ERRORS

-EINVAL

An illegal parameter was passed in.

-EFAULT

Invalid memory area accessed.
