The lowest level of abstraction – Understanding OS-Backed Event Queues, System Calls, and Cross-Platform Abstractions
System calls, FFI, and cross-platform abstractions We’ll implement a very basic syscall for the three architectures: BSD/macOS, Linux, and Windows. We’ll also see how this is implemented in three levels of abstraction. The syscall we’ll implement is the one used when we write something to the standard output (stdout) since that is such a common…
