Function syscall3 

#[unsafe(link_section = ".text")]
pub fn syscall3(n: usize, a1: usize, a2: usize, a3: usize) -> isize

Performs a raw system call with 3 arguments.

This is commonly used for syscalls such as read or write.

Safety

Same as syscall1.

Examples

use azathoth_utils::platform::linux::syscalls::syscall3;

let buf = [0u8; 64];
let n = unsafe { syscall3(0, 0, buf.as_ptr() as usize, buf.len()) }; // read(stdin)
assert!(n >= 0);
