Functions
std::error_code	numapp::ll::SetSchedulerPolicy (pid_t pid, int policy, int static_priority, int dynamic_priority) noexcept
	A low-level, and error prone function to set policy.
std::error_code	numapp::ll::GetSchedulerPolicy (pid_t pid, int *policy, int *static_priority, int *dynamic_priority) noexcept
	A low-level, and error prone function to get policy.
std::error_code	numapp::ll::GetCpuAffinity (pid_t ttid, Cpumask &mask) noexcept
	Get CPU affinity.
std::error_code	numapp::ll::SetCpuAffinity (pid_t ttid, Cpumask const &mask) noexcept
	Set CPU affinity.
std::error_code	numapp::ll::NumaNodeToCpumask (int node, Cpumask &mask) noexcept
	Convert NUMA node number to corresponding CPU mask.
std::error_code	numapp::ll::GetMemPolicy (int &mode, Nodemask &mask, void *addr, unsigned flags) noexcept
	Get memory policy for calling thread or an address.
std::error_code	numapp::ll::SetMemPolicy (int mode, Nodemask const &mask) noexcept
	Set active memory policy for calling thread.
