如何在没有malloc()函数(或calloc())的情况下在linux内核中创建一个缓冲区而没有函数的干净缓冲区free()?
malloc()
calloc()
free()
c malloc free buffer linux-kernel
如何为wait_event_timeout函数设置超时= 1秒?功能:wait_event_timeout (wq,condition,timeout);
wait_event_timeout (wq,condition,timeout);
怎么能超时= 1秒.
如果调用函数那样: wait_event_timeout(queue,flag!='n',30*HZ);
wait_event_timeout(queue,flag!='n',30*HZ);
超时= ???
c timeout time-wait linux-kernel
c ×2
linux-kernel ×2
buffer ×1
free ×1
malloc ×1
time-wait ×1
timeout ×1
