1//! System call interface module.
2//! 
3//! This module provides the system call interface for the Scarlet kernel.
4//! It defines the system call table and the functions that handle various system
5//! calls.
6//! User programs can invoke these system calls to request services from the kernel.
7//! 
8//! ## System Call Table
9//! 
10//! The system call table is a mapping between system call numbers and their
11//! corresponding handler functions. Each entry in the table is defined using the
12//! `syscall_table!` macro.
13//!
