Write a program that copies the content of a file to another file.Usage: cp file_from file_toif the number of argument is not the correct one, exit with code 97 and print Usage: cp file_from file_to, followed by a new line, on the POSIX standard errorif file_to already exists, truncate itif file_from does not exist, or if you can not read it, exit with code 98 and print Error: Can't read from file NAME_OF_THE_FILE, followed by a new line, on the POSIX standard errorwhere NAME_OF_THE_FILE is the first argument passed to your programif you can not create or if write to file_to fails, exit with code 99 and print Error: Can't write to NAME_OF_THE_FILE, followed by a new line, on the POSIX standard errorwhere NAME_OF_THE_FILE is the second argument passed to your programif you can not close a file descriptor , exit with code 100 and print Error: Can't close fd FD_VALUE, followed by a new line, on the POSIX standard errorwhere FD_VALUE is the value of the file descriptorPermissions of the created file: rw-rw-r--. If the file already exists, do not change the permissionsYou must read 1,024 bytes at a time from the file_from to make less system calls. Use a bufferYou are allowed to use dprintf

To solve this problem, we need to write a program that copies the content of one file to another file. The program should be used with the following command line arguments: cp file_from file_to.

First, we need to check if the correct number of arguments is provided. If not, we should exit the program with code 97 and print "Usage: cp file_from file_to" on the POSIX standard error.

Next, we need to check if the file_to already exists. If it does, we should truncate it to ensure we are copying the content to a clean file.

Then, we need to check if the file_from exists and if we have permission to read it. If the file_from does not exist or we cannot read it, we should exit the program with code 98 and print "Error: Can't read from file NAME_OF_THE_FILE" on the POSIX standard error, where NAME_OF_THE_FILE is the first argument passed to the program.

After that, we need to check if we can create or write to the file_to. If we cannot create or write to the file_to, we should exit the program with code 99 and print "Error: Can't write to NAME_OF_THE_FILE" on the POSIX standard error, where NAME_OF_THE_FILE is the second argument passed to the program.

To copy the content of the file_from to the file_to, we should read 1,024 bytes at a time from the file_from using a buffer. This will help us make fewer system calls and improve efficiency.

Finally, we need to ensure that we can close the file descriptors properly. If we cannot close a file descriptor, we should exit the program with code 100 and print "Error: Can't close fd FD_VALUE" on the POSIX standard error, where FD_VALUE is the value of the file descriptor.

The permissions of the created file should be set to rw-rw-r--. If the file already exists, we should not change the permissions.

To achieve this, we can use the dprintf function to print error messages on the POSIX standard error.
