非常感谢@R .. 提醒我一些其他方式，而不是
/dev/psaux
于是，我就
/dev/input/mouse*和
/dev/input/event*
通过使用
cat /proc/bus/input/devices
我得到这个：
I: Bus=0003 Vendor=0461 Product=4d81 Version=0111N: Name="USB Optical Mouse"P: Phys=usb-0000:00:1d.0-1/input0S: Sysfs=/devices/pci0000:00/0000:00:1d.0/usb6/6-1/6-1:1.0/input/input10U: Uniq=H: Handlers=mouse2 event10 B: EV=17B: KEY=70000 0 0 0 0 0 0 0 0B: REL=143B: MSC=10
经过测试，仅
/dev/input/event10适用。代码如下：
#include <stdio.h>#include <unistd.h>#include <linux/input.h>#include <errno.h>#include <fcntl.h>#include <sys/types.h>#include <sys/stat.h>#include <sys/time.h>int main() { struct input_event event, event_end; int fd = open("/dev/input/event10", O_RDWR); if (fd < 0) { printf("Errro open mouse:%sn", strerror(errno)); return -1; } memset(&event, 0, sizeof(event)); memset(&event, 0, sizeof(event_end)); gettimeofday(&event.time, NULL); event.type = EV_REL; event.pre = REL_X; event.value = 100; gettimeofday(&event_end.time, NULL); event_end.type = EV_SYN; event_end.pre = SYN_REPORT; event_end.value = 0; for (int i=0; i<5; i++) { write(fd, &event, sizeof(event));// Move the mouse write(fd, &event_end, sizeof(event_end));// Show move sleep(1);// wait } close(fd); return 0;}
