Linux下如何编程获得当前鼠标位置

Linux下如何编程获得当前鼠标位置,第1张

比如:

#include <stdio.h>

#include <stdlib.h>

#include <linux/input.h>

#include <fcntl.h>

#include <sys/time.h>

#include <sys/types.h>

#include <sys/stat.h>

#include <unistd.h>

int main(int argc,char **argv)

{

int fd, retval

char buf[6]

fd_set readfds

struct timeval tv

//fd = open("/dev/input/mice", O_RDONLY)

if(( fd = open("/dev/input/mice", O_RDONLY))<0)

{

printf("Failed to open \"/dev/input/mice\".\n")

exit(1)

}

else

{

printf("open \"/dev/input/mice\" successfuly.\n")

}

while(1)

{

tv.tv_sec = 5

tv.tv_usec = 0

FD_ZERO(&readfds)

FD_SET(fd, &readfds)

用C语言在Linux下获取鼠标光标的相对位置代码分享:

#include <stdio.h>

#include <stdlib.h>

#include <linux/input.h>

#include <fcntl.h>

#include <sys/time.h>

#include <sys/types.h>

#include <sys/stat.h>

#include <unistd.h>

int main(int argc,char **argv)

{

int fd, retval

char buf[6]

fd_set readfds

struct timeval tv

//fd = open("/dev/input/mice", O_RDONLY)

if(( fd = open("/dev/input/mice", O_RDONLY))<0)

{

printf("Failed to open \"/dev/input/mice\".\n")

exit(1)

}

else

{

printf("open \"/dev/input/mice\" successfuly.\n")

}

while(1)

{

tv.tv_sec = 5

tv.tv_usec = 0

FD_ZERO(&readfds)

FD_SET(fd, &readfds)
