Detailed Description

CPU identification and core affinity types.

Enumeration Type Documentation

core_id

enum class idfxx::core_id : unsigned int

strong

Identifies a specific CPU core.

Use with std::optional<core_id> for core affinity settings, where std::nullopt means "any core".

Note

Only cores available on the target chip are defined. On single-core chips, only core_0 exists.

// Pin task to core 0
.core_affinity = core_id::core_0
 
// Allow task to run on any core
.core_affinity = std::nullopt

Enumerator
core_0

to_string()

std::string idfxx::to_string ( core_id  c )

inline

Returns a string representation of a CPU core identifier.

Parameters

Returns

"CORE_0", "CORE_1" (on multi-core chips), or "unknown(N)" for unrecognized values.
