File operation in C programming(text file method)

2011-02-27T17:43:00.003+08:00

There are two type file operation. One is using text file method and another one using binary file method. The method is for text file method.

First step is to define

FILE *
example :
FILE *ifile;
FILE *book;

Then to open a text file in c programming

function : fopen()
format : fopen("filename",mode);
mode:
"r" = read only
"w" = write only(start from beginning file-replace all previous data)
"a" = write only(start at end file- if got data in the data, it will not be replace)
"r+" = open to update the data(read and write)
"w+"= open to update the data(create,read and write)

example
fopen("book.txt","w");
fopen("new/inputfile.text","r");

note: only one mode in one fopen statement. cannot use"rw". can open a file to write and to read but once open to read must close it first to reopen for write operation.

To write to the text data

function : fprintf()
format : fprintf(FILE *,"",);
example:
fprintf(FILE *ifile, "%d\n", int data);
fprintf(FILE *book,"%c\n", char books);

To read from text file

function: fscanf()
format: fscanf(FILE *,"",);
example:
fscanf(FILE *ifile, "%d\n", int data);
fscanf(FILE *book,"%c\n", char books);

To close the text file

function : fclose()
format: fclose(FILE *);
example:
fclose(ifile);
fclose(book);

Full sequence in a main function

void main()
{
FILE *ifile;
FILE *book;
char books[10];
int data;

fopen("/new/inputfile.text","r");
fopen("book.txt","w");

fscanf(ifile, "%d\n",data);

fprintf(book,"%c\n",books);

fclose(ifile);
fclose(book);

return;
}

Driver Writing Tutorial in Ubuntu 10.04 kernel 2.6.32-27-generic

2011-02-09T13:15:00.012+08:00

Compiling the parlelport.c

1. at the parlelport.c directory

2. the command below is using the admin account

3. type “make –C /lib/modules/(current kernel)/build/ M=$(pwd) modules”

a. sudo make –C /lib/modules/2.6.32-27-generic/build/ M=$(pwd) modules

b. then type the admin password

4. The compiling will do the process as shown in figure below.

Inserting the module/driver in the kernel system

1. Login as admin

2. To insert type “insmod ”

a. sudo insmod parlelport.ko

b. after the driver compiled, it will generate filetype *.ko in the same directory. This will be use when we want to insert the driver in the kernel.

3. To check the module is in the kernel or not type “lsmod”

4. We can see that in figure below parlelport is in the kernel by size 1552 byte

Remove the module/driver

1. Login as admin

2. To remove the module type “rmmod ”

a. sudo rmmod parlelport.ko

3. To check the module again using “lsmod”

4. We can see the parlelport module is not in the list below.]

Port usage in the kernel

1. In the parlelport.c we already using a command in the function once the driver connected to request a port to assign to the driver.

2. In the parlelport.c, we request using the command below

a. request_region(0x378,1,"parlelport");

b. this command will request the kernel to reserve and assign the requested port for the driver to use.

c. In this command, requested port is 0x378 using parlelport as it label.

3. We can see in figure below. The parlelport is using 0378-0378 as it port once the driver is insert in the kernel using insmod command.

4. Once the rmmod command is used to remove the driver, it also request the kernel to release the port assigned before using :

a. release_region(0x378,1);

how to install windows vista or seven using pendrive...

2010-04-01T17:40:00.000+08:00

hi everyone... here what i found on the internet about how to install windows vista or seven using pendrive...

Source : Into Windows

This guide works 100% for Vista & Windows 7 unlike most of the guides out there. I have seen many sites/blogs that have “Install Vista from USB guide” but either with incomplete steps or not working guide. I have also seen some guides that don’t’ use proper commands in this guide. After spending many hours I have come up with this 100% working guide.

I just did this method on one of my friends machine and installed the new Windows 7 BETA. The main advantage is that by using USB drive you will be able to install Windows 7/Vista in just 15 minutes. You can also use this bootable USB drive on friend’s computer who doesn’t have a DVD optical drive.

The method is very simple and you can use without any hassles. Needless to say that your motherboard should support USB Boot feature to make use of the bootable USB drive.

Requirements:

*USB Flash Drive (Minimum 4GB)

*Windows 7 or Vista installation files.

Follow the below steps to create bootable Windows 7/Vista USB drive using which you can install Windows 7/Vista easily.

1. Plug-in your USB flash drive to USB port and move all the contents from USB drive to a safe location on your system.

2. Open Command Prompt with admin rights. Use any of the below methods to open Command Prompt with admin rights.

*Type cmd in Start menu search box and hit Ctrl+ Shift+ Enter.

*Go to Start menu > All programs > Accessories, right click on Command Prompt and select Run as administrator.

3. You need to know about the USB drive a little bit. Type in the following commands in the command prompt:

First type DISKPART and hit enter to see the below message.

Next type LIST DISK command and note down the Disk number (ex: Disk 1) of your USB flash drive. In the below screenshot my Flash Drive Disk no is Disk 1.

4. Next type all the below commands one by one. Here I assume that your disk drive no is “Disk 1”.If you have Disk 2 as your USB flash drive then use Disk 2.Refer the above step to confirm it.

So below are the commands you need to type and execute one by one:

SELECT DISK 1

CLEAN

CREATE PARTITION PRIMARY

SELECT PARTITION 1

ACTIVE

FORMAT FS=NTFS

(Format process may take few seconds)

ASSIGN

EXIT

Don’t close the command prompt as we need to execute one more command at the next step. Just minimize it.

5. Next insert your Windows7/Vista DVD into the optical drive and check the drive letter of the DVD drive. In this guide I will assume that your DVD drive letter is “D” and USB drive letter is “H” (open my computer to know about it).

6. Maximize the minimized Command Prompt in the 4th step.Type the following command now:

D: CD BOOT and hit enter.Where “D” is your DVD drive letter.

CD BOOT and hit enter to see the below message.

7. Type another command given below to update the USB drive with BOOTMGR compatible code.

BOOTSECT.EXE /NT60 H:

Where “H” is your USB drive letter. Once you enter the above command you will see the below message.

8. Copy your Windows 7/Vista DVD contents to the USB flash drive.

9. Your USB drive is ready to boot and install Windows 7/Vista. Only thing you need to change the boot priority at the BIOS to USB from the HDD or CD ROM drive. I won’t explain it as it’s just the matter the changing the boot priority or enabling the USB boot option in the BIOS.

Note: If you are not able to boot after following this guide means you haven’t set the BIOS priority to USB. If you got any problem in following this guide feel free to ask questions by leaving comment.

Update: If you find this guide difficult to follow, please use the easy-to-use guide to create a bootable USB to install Windows 7 using official tool.
