Function twizzler_abi::arch::syscall::raw_syscall

pub unsafe fn raw_syscall(call: Syscall, args: &[u64]) -> (u64, u64)

Call into the kernel to perform a synchronous system call. The args array can be at most 6 long, and the meaning of the args depends on the system call. The kernel can return two 64-bit values, whose meaning depends on the system call.

You probably don’t want to call this function directly, and you should instead use the wrappers in crate::syscall.

Safety

The caller must ensure that the args have the correct meaning for the syscall in question, and to handle the return values correctly. Additionally, calling the kernel can invoke any kind of weirdness if you do something wrong.
