TTMSMCPTaskRegistry.MarkTaskInUse Method

Protects a task from being purged while a blocking request is reading it or waiting on it.

API unit family: TMS.MCP.Tasks Declaring type: TTMSMCPTaskRegistry

Syntax

procedure MarkTaskInUse(const ATaskId: string; AInUse: Boolean);

Remarks

Users are counted, so concurrent readers nest safely. TTMSMCPTaskRegistry.PurgeExpiredTasks skips a task that has at least one user. Does nothing when the identifier is unknown.

Parameters

Name	Description
ATaskId	Identifier of the task to mark.
AInUse	True registers one more user of the task, False releases one. Every call with True must be matched by a call with False.
