stdbasiciospostype

stdbasiciospostype is a hypothetical data structure proposed to standardize asynchronous input/output posting in a family of BASIC-inspired standard libraries. The term integrates std (standard), basic (BASIC-family languages), io (input/output), post (queue or post-operation), and type (descriptor), signaling a portable descriptor that represents a single I/O operation slated for execution by an asynchronous engine.

Definition and role

In typical designs, stdbasiciospostype is a lightweight, language-agnostic descriptor used to queue I/O requests to an event loop, dispatcher, or thread pool. It encapsulates all information necessary to perform a specific I/O action and to report its result back to the caller in a non-blocking manner.

Structure and fields

A stdbasiciospostype generally includes fields such as an operation kind (for example, READ, WRITE, OPEN, CLOSE, FLUSH, SEEK), a handle or file descriptor identifying the target resource, a data buffer reference and length, an optional offset, a status or error code, and a completion mechanism (such as a callback or token for a future/promise). Memory ownership and lifetime rules are typically defined by the surrounding library to prevent leaks or races.

Usage model

Applications create and populate a stdbasiciospostype, submit it to the I/O subsystem, and continue work. The subsystem processes the request asynchronously and communicates completion through the chosen mechanism. This model helps separate application logic from platform-specific I/O calls and supports scalable, non-blocking I/O patterns.

Relation to other concepts

stdbasiciospostype is related to broader concepts like asynchronous I/O, event loops, and post queues. It parallels structures used in operating systems’ I/O completion ports, epoll-based systems, or future/puture-based APIs, but framed for a standardized BASIC-like library.

Status

As a conceptual construct, stdbasiciospostype is not part of a widely adopted standard. It appears in theoretical discussions about standardizing async I/O in BASIC-family ecosystems and may influence future library designs. See also: standard I/O, asynchronous I/O, event loop, post queue.
