In computing , a system call commonly abbreviated to syscall is the programmatic way in which a computer program requests a service from the kernel of the operating system on which it is executed. This may include hardware-related services for example, accessing a hard disk drive , creation and execution of new processes , and communication with integral kernel services such as process scheduling. System calls provide an essential interface between a process and the operating system.
