Function Documentation

BLI_task_parallel_mempool()

void BLI_task_parallel_mempool	(	struct BLI_mempool *	mempool,
		void *	userdata,
		TaskParallelMempoolFunc	func,
		const TaskParallelSettings *	settings )

This function allows to parallelize for loops over Mempool items.

Parameters

mempool	The iterable BLI_mempool to loop over.
userdata	Common userdata passed to all instances of func.
func	Callback function.
settings	See public API doc of TaskParallelSettings for description of all settings.

Note

There is no static scheduling here.
