Member Function Documentation

MakeFromCpuString()

static Cpumask numapp::Cpumask::MakeFromCpuString ( char const * cpustring )

inlinestaticnodiscard

Construct Cpumask from cpustring that considers current cpuset.

Note

Uses numa_parse_cpustring to parse.

Related man-page(s):

• numa(3)

Parameters

cpustring

Mask expressed as cpustring in the form of comma separated list of cpu numbers or ranges, e.g. 1,3-8. See man page for additional details.

Exceptions

std::system_error

containing error code if parsing fails.

Definition at line 63 of file cpumask.hpp.

MakeFromCpuStringAll()

static Cpumask numapp::Cpumask::MakeFromCpuStringAll ( char const * cpustring )

inlinestaticnodiscard

Note

Uses numa_parse_cpustring_all to parse.

Related man-page(s):

• numa(3)

Parameters

cpustring

Mask expressed as cpustring in the form of comma separated list of cpu numbers or ranges, e.g. 1,3-8. See man page for additional details.
