Detailed Description

Own native thread ports and the Mach allocated thread array.

Constructor & Destructor Documentation

macOS_thread_resources() [1/2]

mysql::system_info::internal::macOS_thread_resources::macOS_thread_resources	(	thread_act_array_t	threads,
		mach_msg_type_number_t	thread_count,
		macOS_thread_deallocator	deallocator
	)

Take ownership of the thread ports and array returned by task_threads().

macOS_thread_resources() [2/2]

mysql::system_info::internal::macOS_thread_resources::macOS_thread_resources ( const macOS_thread_resources &  )

delete

~macOS_thread_resources()

mysql::system_info::internal::macOS_thread_resources::~macOS_thread_resources

(

)

Release owned Mach resources if the collector has not released them.

operator=()

macOS_thread_resources & mysql::system_info::internal::macOS_thread_resources::operator= ( const macOS_thread_resources &  )

delete

release()

std::error_code mysql::system_info::internal::macOS_thread_resources::release

(

)

Release every owned right and the thread array exactly once.

Release the thread ports and allocated array returned by task_threads().

Each thread port is a 'send right' owned by the caller. The array itself is memory allocated by Mach. Release all ports even if one release fails, then release the array. The first error is retained. Repeated calls return the error without releasing anything again.
