Typedef Documentation

Atomic_xor_of_thread_id

using Atomic_xor_of_thread_id = Atomic_xor_of_things<std::thread::id, Xor_digit_for_thread_id>

A type to store XORed objects of type std::thread::id.

os_thread_id_t

using os_thread_id_t = std::thread::native_handle_type

Operating system thread native handle.

Xor_digit_for_thread_id

using Xor_digit_for_thread_id = std::conditional<sizeof(std::thread::id) >= sizeof(uint64_t), uint64_t, uint32_t>::type

A type for std::thread::id digit to store XOR efficiently.

This will make the compiler to optimize the operations hopefully to single instruction.

Function Documentation

to_string()

std::string to_string	(	std::thread::id	thread_id,
		bool	hex_value = false
	)

Returns the string representation of the thread ID supplied.

It uses the only standard-compliant way of printing the thread ID.

Parameters

thread_id	The thread ID to convert to string.
hex_value	If true, the conversion will be asked to output in hexadecimal format. The support for it is OS-implementation-dependent and may be ignored.
