future boost::afio::dispatcher::close

(

const std::vector< future<>> &

ops

)

[pure virtual]

Schedule a batch of asynchronous file or directory handle closes after preceding operations.

Note this is ignored for handles where available_to_directory_cache() is true as those cannot be explicitly closed. Note that failure to explicitly schedule closing a file handle using this call means it will be [*synchronously] closed on last reference count by `__afio_handle__`. This can consume considerable time, especially if SyncOnClose is enabled.

Returns:

A batch of op handles.

Parameters:

ops	A batch of op handles.

future boost::afio::async_close

(

future<>

_precondition

)

Asynchronous file or directory handle close after a preceding operation.

Returns:

A future<void>

Parameters:

_precondition

The precondition to use.

{Amortised O(1) to dispatch. Amortised O(1) to complete if closing handles is constant time.} {filedir_example}

Definition at line 4975 of file afio.hpp.

void boost::afio::close

(

future<>

_precondition

)

Synchronous file or directory handle close after a preceding operation.

Parameters:

_precondition

The precondition to use.

{distinguish, throwing} {Amortised O(1) to dispatch. Amortised O(1) to complete if closing handles is constant time.} {filedir_example}

Definition at line 4990 of file afio.hpp.

void boost::afio::close	(	error_code &	_ec,
		future<>	_precondition
	)

Synchronous file or directory handle close after a preceding operation.

Parameters:

_ec	Error code to set.
_precondition	The precondition to use.

{distinguish, non throwing} {Amortised O(1) to dispatch. Amortised O(1) to complete if closing handles is constant time.} {filedir_example}
