about file reading wait time...

about file reading wait time...

imagem de nineye


When I read file, I think CPU is stopped until read work is finished.
I guessed that the time of CPU waitting is added to "wait time".
but the wait time of read function is 0.
How can I understand this issue.
Does CPUwork infinit loop until read end?

Please Answer about my question.
