IMPLEMENTATION OF LINUX SYSTEM CALL

[stat()]

AIM:

To write a C program to know the status of the file using LINUX system call stat().

ALGORITHM:

Step1: Start the process.

Step2: Define a structure stat.

Step3: Declare two unsigned variables for storing the address and total size of the file

Step4: Specify the filename and check the status of file using stat() system call

Step5: Print the address and size of the file.

Step6: Stop the process.

PROGRAM:

#include<sys/stat.h>

#include<stdio.h>

int main()

{

Struct stat s;

unsigned long a;

unsigned long b;

if(stat(“test.c”,&s)==(-1))

{

perror(“Error:cannot stat file”);

exit(EXIT_FAILURE);

}

a=s.st_blksize;

b=s.st_size;

printf(“%u \t %u \n”,a,b);

return 0;

}

OUTPUT:

gcc stat.c

address:4096                          total size:52
