PR_ClearInterrupt 编辑

Clears the interrupt request for the calling thread.

Syntax

#include <prthread.h>

void PR_ClearInterrupt(void);

Description

Interrupting is a cooperative process, so it's possible that the thread passed to /wiki/en-US/docs/Mozilla/Projects/NSPR/Reference/PR_Interrupt may never respond to the interrupt request. For example, the target thread may reach the agreed-on control point without providing an opportunity for the runtime to notify the thread of the interrupt request. In this case, the request for interrupt is still pending with the thread and must be explicitly canceled. Therefore it is sometimes necessary to call PR_ClearInterrupt to clear a previous interrupt request.

If no interrupt request is pending, PR_ClearInterrupt is a no-op.
