Odin Rqt-close May 2026

import "core:runtime" cleanup_my_resource :: proc(data: rawptr) handle := cast(^windows.HANDLE)data CloseHandle(handle^)

init_program :: proc() my_handle := CreateFile(...) runtime.add_cleanup(cleanup_my_resource, &my_handle) odin rqt-close

Or for a cross-platform abstraction:

if my_handle != INVALID_HANDLE CloseHandle(my_handle) my_handle = INVALID_HANDLE rqt-close is not a magic keyword or a hidden runtime feature

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. or allocated system object

rqt-close is not a magic keyword or a hidden runtime feature. It is a discipline . By writing an explicit close for every opened file, created handle, or allocated system object, you retain full control over your program’s interaction with the operating system.
