摘要
Input/output (I/O) interrupts are avoided at the completion of I/O operations. A task requests (implicitly or explicitly) an I/O operation, and processing of the task is suspended awaiting completion of the I/O operation. At the completion of the I/O operation, instead of an I/O interrupt, an indicator associated with the task is set. Then, when the task once again becomes the current task to be executed, the indicator is checked. If the indicator indicates the I/O operation is complete, execution of the task is resumed.
