很久以前的代码拿出来了!熟悉linux键盘驱动的这段代码太容易啦!
/*获取键盘的按值*/ #include <stdio.h> #include <linux/input.h> #include <stdlib.h> #include <fcntl.h> #include <assert.h> struct info { struct timeval time; unsigned short type; unsigned short code; unsigned int value; }; int main() { int fd; struct info node; fd = open("/dev/input/event0",O_RDWR); if(fd<0) { printf("open error!\n"); } //assert(fp); while(1) { long i=0; fflush(stdout); read(fd,&node,sizeof(struct info)); if(node.type == EV_KEY) { printf("code :%d\n",node.code); printf("value: %d\n",node.value); } } }
