Tip: Return the application when the buffer is full Program ; The input buffer is only used for mutually exclusive messages; Before the buffer is transmitted to midiinaddbuffer, call midiinprepareheader preparation and globalalloc to allocate memory to the tmidihdr and the buffer directed by lpdata (gmem_moveable and gmem_share are used) and use globallock to lock the buffer. // Declaration: midiinaddbuffer (hmidiin: hmidiin; {

Linux input device is an important subsystem. Before introducing an instance, let's take a look at the related APIs. Linux Input Device Input. C is a Linux "input" driver that mainly supports keyboard and mouse

Due to work relationships, attention to Android will shift from FWK (Framework) to BSP, that is, Linux Kernel. In the five years at work, I have studied kernel several times, but I have never had the right opportunity or motivation to study it in depth. How can I leave this opportunity? In the past, we used to work with kernel and always felt that there were no suitable devices. After several days, I plan to start with the android Virtual Device goldf

These two days in the study of Linux input-polldev.c, which is a new architecture provided by kernel, the architecture based on the original Linux input subsystem, added a layer of polling device encapsulation outside the input device. This architecture allows us to register
