Odin’s lack of automatic cleanup is a feature, not a bug. It forces you to think about resource lifetimes at every step, leading to more predictable and often more efficient software. The rqt-close pattern—whether you name it that or simply call CloseHandle directly—is the cornerstone of robust system programming in Odin.
Example:
close_resource :: proc(resource: ^Raw_Resource) when ODIN_OS == "windows" sys.windows.CloseHandle(resource.handle) else when ODIN_OS == "linux" sys.linux.close(resource.fd) resource.valid = false odin rqt-close
when ODIN_OS == "windows" close_fn :: proc(h: rawptr) windows.CloseHandle(transmute(windows.HANDLE)h) else when ODIN_OS == "linux" || ODIN_OS == "darwin" close_fn :: proc(fd: rawptr) sys.linux.close(transmute(int)fd) Odin’s lack of automatic cleanup is a feature, not a bug
A typical Odin solution uses conditional compilation: odin rqt-close
