Performs a raw syscall and returns a SyscallWord.

Prefer syscall! unless you are certain the syscall cannot fail (e.g., gettid).

Accepts a syscall number and a variable number of arguments (0 to 6).

Example

use rawsys_linux::{Sysno, raw_syscall};
let tid = unsafe { raw_syscall!(Sysno::gettid) };
println!("tid={tid}");
