Module kernel::syscall

Module for processing syscall

All functions that begin with sys_ will extract parameters from trap frame, turn pointers into Rust primitives and call corresponding functions with these parameters in kernel code.

For specifications and how to do syscalls, refer to syscall module in user crate.

Re-exports

pub use gen::*;

Modules

file	File-related syscalls
gen	This module is automatically generated with syscall_gen.rs.py, which contains all syscall ID.

Functions

arg_fd	Get file corresponding to a file descriptor
arg_int	Get the posth argument as i32 from syscall
arg_ptr	Get the posth argument as a pointer from syscall, return kernel-space pointer (involve security issues!)
arg_ptr_mut	Get the posth argument as a pointer from syscall, return kernel-space mutable pointer (involve security issues!)
arg_uint	Get the posth argument as usize from syscall
argraw	Get the posth argument from syscall
sys_exec	exec syscall entry
sys_exit	exit syscall entry
sys_fork	fork syscall entry
syscall	Process all syscall
