File handling system calls are a subset of system calls that are specifically used for managing files. These system calls allow processes to create, open, read, write, and delete files. They also allow processes to get information about files, such as their size, permissions, and creation date. Some of the most common file handling system calls include: open(): : Opens a file for reading or writing. read(): : Reads data from a file. write(): : Writes data to a file. close(): : Closes a file. unlink(): : Deletes a file. stat(): : Gets information about a file.

File handling system calls are a subset of system calls that are specifically used for managing files. These system calls allow processes to create, open, read, write, and delete files. They also allow processes to get information about files, such as their size, permissions, and creation date.

Some of the most common file handling system calls include:
open(): : Opens a file for reading or writing.
read(): : Reads data from a file.
write(): : Writes data to a file.
close(): : Closes a file.
unlink(): : Deletes a file.
stat(): : Gets information about a file.

File handling system calls are essential for any process that needs to access files. By using these system calls, processes can read and write data to files, create and delete files, and get information about files.

Here are some examples of how file handling system calls can be used:
A text editor might use the open() system call to open a file for reading, the read() system call to read the contents of the file, and the write() system call to write changes to the file.
A web browser might use the open() system call to open an HTML file for reading, the read() system call to read the contents of the file, and the close() system call to close the file once it is finished reading it.
A compiler might use the open() system call to open a source code file for reading, the read() system call to read the contents of the file, and the close() system call to close the file once it is finished reading it.
