Function linux_syscalls::raw_syscall5_readonly

pub unsafe fn raw_syscall5_readonly(
    sysno: Sysno,
    arg0: usize,
    arg1: usize,
    arg2: usize,
    arg3: usize,
    arg4: usize
) -> usize

Make a raw system call with 5 arguments. Like the non _readonly version but you declare that syscall does not mutate any memory.

Returns a raw usize, doesn’t not check for errors.

Safety

A system call is unsafe by definition. It’s the caller’s responsibility to ensure safety.
