What is the method for interfacing with Linux system calls?

The method for using system calls in the Linux operating system interface is through system calls. System calls act as the interface between applications and the operating system kernel, allowing applications to request the operating system to perform specific tasks such as file operations, process management, and network communication. In Linux, applications trigger system calls by using interfaces provided by library functions (such as glibc), which ultimately call the corresponding functions in the kernel to carry out the operation. Common system calls include open, read, write, and close.
