Access control is sometimes critical for the reliability of a device node. This part of content is only modified on the open and release methods, and some check mechanisms are added. Exclusive Device The most rigid access control method is to allow a device to be opened (exclusive) by a single process at a time, which is the simplest access control for a

Note that the PC driver needs to be added in two modules, respectively in the [Google. ntx86] section and [Google. ntamd64] adds the segment (applicable to CPUs on different PCs), so that these three values correspond to the model. After we pass these parameters of this model to, they will match these parameters with the model. In this way, th
