linux 下c编程，监控文件中的inotif怎么样才能监控到共享方式的文件夹？

inotify can not monitor nfs or samba

two way to do it :

1>File Alteration Monitor(known as FAM and sgi_fam, provides a subsystem developed by Silicon Graphics for Unix-likeoperating systems.)

server runs at nfs server ,while client runs at client pc

2>server runs a program using inotif monitor file changs ,then send changs to remote client by socket. it is a question of adding some socket ipc to your client progarm.

int movefile()

{

DIR *dir

struct dirent *dt

FILE *fp1,*fp2

char filename1[256],filename2[256]

char buf[1024]

int readsize,writesize

if((dir = opendir(SRCPATH)) == NULL)

{

printf("opendir %s error\n",SRCPATH)

return -1

}

memset(filename1,0,sizeof(filename1))

strcpy(filename1,SRCPATH)

memset(filename2,0,sizeof(filename2))

strcpy(filename2,DSTPATH)

while(1)

{

while((dt = readdir(dir)) != NULL)

{

if(strcmp(dt->d_name,".")==0||strcmp(dt->d_name,"..")==0)

{

continue

}

//如果这个目录里 还有目录，可以在这加判断

//这里假设初始为空目录

strcat(filename1,dt->d_name)

strcat(filename2,dt->d_name)

//如果进程资源较少可以直接用linux系统命令

fp1 = fopen(filename1,"rb")

if(fp1==NULL)

{

printf("open %s failed /n",filename1)

return -1

}

fp2 = fopen(filename2,"wb")

if(fp2==NULL)

{

printf("open %s failed /n",filename2)

fclose(fp1)

return -1

}

while((readsize = fread(buf,sizeof(buf),1,fp1))>0)

{

//total += readsize

memset(buf,0,sizeof(buf))

writesize = fwrite(buf,sizeof(buf),1,fp2)

if(writesize!==readsize)

{

printf("write error")

return -2

fclose(fp1)

fclose(fp2)

}

}

fclose(fp1)

fclose(fp2)

rmdir(filename2)

}

}

}

int main(int argc,char **argv)

{

pthread_t id1

int ret

ret = pthread_create(&id1, NULL, (void*)movefile, NULL)

return ret

}

自己调试下
