Integrating Application code[User Space] in Kernel.

Dear All,

Please Look in the below Code  : consider the Name of File Test.c

Consider this as reference file.

int main(int argc,char **argv)
{
    int fd=open("/dev/samsungled",O_RDWR);
    int arg;
    if(argc==1)
        arg=0x00;
    else if(argc==2)    
    {
        arg=atoi(argv[1]);
    }
    if(arg>15)
        arg=0;
    
    printf("%d\n",arg);    
    
    printf("=============TEST BEGIN=============\n");
    if(fd == -1)
    {
        printf("Open File Error\n");
        exit(0);
    }

    if(ioctl(fd,arg,0)==-1)
    {
        printf("Ioctl Error\n");
        exit(0);
    }
    printf("==============TEST END===============\n");

    close(fd);
}

I have  added the Device Driver Module for Blinking LED with Some IOCTL calls in the Kernel. Under driver directory.

I have to Link the Application Code i.e this file with the kernel or consider that I have already register device of UART. i have to access the UART receive and Transmit function if i write a application code somewhat in this manner.

1. In which folder should i Place the Files.

2. How the Files will be Linked with kerenel.

Please Your Guidence is needed. I am Using TAM-3517 standard board and Kernel is LInux-2.6.32.

Thanks and Regard's
